Quick answer
Started on 1 March 2018, you have 8 years, 8 months and 6 days of service as of 7 November 2026, with 3,173 days and 2,266 weekdays behind you. The calculator shows your next anniversary, your service milestones from 1 to 30 years, and when you qualify for a sabbatical.
This calculator gives a calendar figure for planning. It does not apply any employment law, contract term or company policy, and it is not legal advice. When a calculation affects pay, leave or legal rights, use the exact dates from your employment contract or payroll records and check the rule that applies.
The Work Tenure Calculator shows how long you have worked at a job, in years, months and days, with your total days, the weekdays worked, your next work anniversary and the dates of your service milestones. It can also show when you become eligible for a sabbatical or long-service leave.
How to Use the Work Tenure Calculator
Enter the date you started the job: pick the day and month, and type the year. Leave “Calculate as of” blank for today, or type a different date to check, such as a leaving date.
Optionally enter the number of years of service your employer requires for a sabbatical or long-service leave. Select Calculate. Three quick chips sit below the form: 1 March 2018, 15 September 2010, and 6 January 2025.
Each one calculates at once. Leave the start date empty and the tool replies: “Enter the date you started the job.” An impossible date is met with: “One of the dates is not valid.
Please check it.” A start date that falls after the as-of date is turned away with: “The start date is after the date you are calculating for.”
The result shows your length of service in the big line, for example “8 years, 8 months, 6 days”, and the line underneath reads “From Saturday, 1 March 2018 to Saturday, 7 November 2026 (today).
Your 9th work anniversary is on Monday, 1 March 2027.” The stats show the total days and the weekdays worked, and the next anniversary with the days left to it. Below that, the milestone list shows seven dates, 1, 5, 10, 15, 20, 25 and 30 years, each marked “Reached” or “In N days”.
If you entered a sabbatical rule, a note reads “Eligible for leave after 10 years on Monday, 1 March 2028, in 480 days. Check your employer’s policy for the exact rule.” or, when the date has passed, “Eligible for leave after 7 years since Saturday, 1 March 2025.”
For the time between any two dates, use the Days Between Dates calculator. For working days with holidays excluded, use the Business Days Calculator.
How Length of Service Is Counted
The calculator counts completed years, then completed months, then the remaining days from your start date, using real month lengths and every leap year. Your start date is day zero, so on the day before your first anniversary you have 11 months and some days of service, and on the anniversary itself exactly 1 year.
If you started on the 29th, 30th or 31st of a month, a month of service is completed on the last day of shorter months, the same month-end rule used on every Age-Finder calculator. Someone who started on 29 February counts their anniversary on 28 February in common years.
The weekdays figure counts Monday to Friday between your start date and the date you calculate for. The start date counts if it is a weekday; the as-of date does not.
It does not remove public holidays, annual leave or part-time patterns, so treat it as the number of working weekdays in the period rather than the days you actually worked.
Worked Example
Someone who started on 1 March 2018 has, on 7 November 2026: 8 years, 8 months and 6 days of service. 3,173 days in total. 2,266 weekdays. Their 9th work anniversary on 1 March 2027, in 114 days.
Their 10-year milestone on 1 March 2028, in 480 days. In decimal years, 3,173 days divided by 365.25 is 8.69 years. In weeks, 3,173 days is 453.29 weeks.
The other two chips give the same treatment. Started 15 September 2010, you have 16 years, 1 month and 23 days of service as of 7 November 2026, with 5,897 days behind you.
Started 6 January 2025, you have 1 year, 10 months and 1 day, with 670 days behind you, and your 2nd work anniversary is on 6 January 2027.
Work Anniversaries and Service Milestones
Many employers mark service milestones with awards, extra leave or pension changes. The result lists each milestone date and shows how many days remain, so you can plan ahead or remind a colleague. The tool lists seven milestones, from 1 year to 30 years:
| Milestone | Date | Status on 7 November 2026 |
|---|---|---|
| 1 year | 1 March 2019 | Reached 2,808 days ago |
| 5 years | 1 March 2023 | Reached 1,347 days ago |
| 10 years | 1 March 2028 | In 480 days |
| 15 years | 1 March 2033 | In 2,306 days |
| 20 years | 1 March 2038 | In 4,132 days |
| 25 years | 1 March 2043 | In 5,958 days |
| 30 years | 1 March 2048 | In 7,785 days |
Day counts matter too, and the tool does not show them, so the guide gives them here. For the same start date, 1 March 2018, the 90-day probation mark falls on 30 May 2018 and the 180-day mark on 28 August 2018. Day 1,000 is Wednesday, 25 November 2020.
Day 5,000 is Saturday, 8 November 2031. Day 10,000 is Monday, 17 July 2045. One warning: 1,825 days is not exactly 5 years. 1 March 2018 plus 1,825 days is 28 February 2023, one day before the 5-year milestone, because the leap day of 29 February 2020 falls inside the span.
Decimal Years
The tool does not show decimal years, so the guide works them by hand.
Three methods agree for the worked example: 3,173 days divided by 365.25 is 8.69 years; divided by 365.2425, the average Gregorian year, it is also 8.69 years; and (104 full months plus 6 days divided by 30) divided by 12 is 8.69 years.
For the test date, 14 May 1990 to 7 November 2026, 13,326 days divided by 365.25 is 36.48 years. Use the decimal figure for severance formulas, pension vesting and equity schedules, which usually ask for years to two decimal places, and the years-and-months figure for CVs and service awards.
Multiple Jobs and Team Averages
The calculator measures one continuous period. For broken service, calculate each period separately and add them, and check whether your employer counts breaks. For example, Job A from 1 March 2018 to 30 June 2021 is 3 years, 3 months and 29 days, or 39 months and 1,217 days.
Job B from 1 September 2021 to 7 November 2026 is 5 years, 2 months and 6 days, or 62 months and 1,893 days. Together that is 101 months, or 8 years and 5 months. Add the months, not the years and days separately, or the days will double count.
To average tenure across a team, add the months for each person and divide by the number of people. Five people with 8 years 8 months (104 months), 3 years 2 months (38 months), 12 years (144 months), 1 year 6 months (18 months) and 5 years 4 months (64 months) total 368 months.
Divided by 5, the average is 73.6 months, or 6 years and 1.6 months. The median is a better figure than the average for a team, because one long-serving person pulls the average up: in this example the median is 5 years and 4 months.
Sabbaticals and Long-Service Leave
Some employers offer a sabbatical after a set number of years, and some countries have long-service leave laws. In Australia, for example, long-service leave is usually available after 7 to 10 years with the same employer, depending on the state or territory.
The Fair Work Ombudsman says most employees’ entitlement comes from long-service leave laws in each state or territory, which set out how long an employee must work to get it, for example after 7 years, and how much leave they get.
The Fair Work Ombudsman page on long service leave also lists the portable schemes: all states and territories have legislation for building and construction, contract cleaning, community services and security, plus a national scheme for coal mining, so the entitlement follows the worker between employers in those industries.
Enter the number of years in your policy and the calculator shows the date you become eligible and how many days remain. For the worked example, started 1 March 2018, a 7-year rule gives eligibility on 1 March 2025, already reached, and a 10-year rule gives 1 March 2028, in 480 days.
The rules for leave, notice periods and benefits are set by employment contracts, company policies and local law, so check the exact wording. Some schemes count continuous service only, some include breaks, and some count from a probation end date rather than the first day.
How Your Tenure Compares
The US Bureau of Labor Statistics measures tenure the same way this tool does, as continuous time with the current employer, and its Employee Tenure release put the median at 4.1 years in January 2026, up from 3.9 years in January 2024.
The survey runs every two years as a supplement to the Current Population Survey, with about 60,000 households.
| Group | January 2026 | January 2024 |
|---|---|---|
| All workers | 4.1 years | 3.9 years |
| Men | 4.3 years | 4.2 years |
| Women | 4.0 years | 3.6 years |
| Private sector | 3.9 years | 3.5 years |
| Public sector | 5.6 years | 6.2 years |
The median rises with age: workers 25 to 34 had a median of 3.0 years in January 2026, up from 2.7 in 2024, while workers 55 to 64 had 9.6 years, unchanged.
By industry, financial activities had the highest median at 5.0 years, with mining, quarrying and oil and gas extraction, manufacturing and information all at 4.9, and leisure and hospitality the lowest at 2.4 years. By occupation, management roles had the longest median at 6.1 years, and food preparation and serving the shortest at 2.2 years.
The share of workers with a year or less of tenure was 20.6 percent in January 2026, down from 22.2 percent in 2024. Against that background, 8 years and 8 months with one employer is roughly double the US median, and 16 years is roughly four times it.
The Day-One Convention
Not every calculator counts the same way. Some count the start date as day 1 and the last day as a full day, so the same period reads one day longer.
On that convention, starting on 2 March 2021 and working through 1 March 2022 makes exactly 1 year.
This calculator counts the start date as day zero, the same convention as the Age Calculator and Excel’s DATEDIF, so the anniversary itself is exactly 1 year and the day before it is 11 months and 27 days.
When you compare figures from two calculators, check which convention each one uses before concluding that one of them is wrong.
Why Your Length of Service Matters
Length of service, also called tenure or seniority, can affect: Notice periods, which often increase with years of service. Redundancy or severance pay, which is often calculated per year of service.
Pension or retirement plan vesting. Extra annual leave or service awards. Eligibility for internal promotions or sabbaticals. When a calculation affects pay or legal rights, use the exact dates from your employment contract or payroll records.
In the United States, the Family and Medical Leave Act adds a second test on top of the 12 months: an employee must also have at least 1,250 hours of service in the 12 months before the leave starts, and work at a location where the employer has at least 50 employees within 75 miles.
The calculator counts calendar time only; it cannot measure hours.
Celebrating Work Anniversaries
Work anniversaries are a simple way to recognise colleagues. Managers and HR teams often keep a list of start dates and check upcoming milestones each month. Enter each start date to find the next anniversary and how many days remain, then plan a message, card or award.
Traditional milestone gifts include a certificate or pin at 5 years and larger awards at 10, 20 and 25 years, but every organisation sets its own customs.
Tenure on a CV or Application
Applications and CVs usually ask for employment dates as months and years, such as March 2018 to present.
If a form asks for total experience, the calculator’s years and months give an accurate figure; round down rather than up, so 8 years and 8 months becomes “8 years” or “over 8 years”. For several jobs, calculate each period and add the months together.
How This Calculator Compares
Three years-of-service calculators rank for the same query, and each one measures the same period in its own way. The table below lays them out side by side.
| Feature | This page | CalculatorZilo | Roberin | AgeCalculatorLab |
|---|---|---|---|---|
| Free, no account, no sign-up, no download | Yes | Yes | Yes | Yes |
| Years, months and days of service | Yes | Yes | Yes | Yes |
| Total days and weeks | Yes, days | Yes, days and weeks | Yes, days and weeks | Yes, days |
| Weekdays worked | Yes | Yes, business days | Yes | Yes, estimated |
| Decimal years | No, in the guide | No | Yes | Yes |
| Next anniversary and milestones | Yes, 1 to 30 years | Yes, day counts | Yes, plus day 1,000 | Yes |
| Sabbatical eligibility | Yes | No | No | No |
| BLS median tenure data | Yes, in the guide | Yes | Yes | No |
| Team-average mode | No, in the guide | No | No | No |
| Multi-job totals | No, in the guide | No | No | Yes, add a period |
Where this page stops: it shows no BLS median tenure data, no team-average mode, no multi-job totals and no decimal years. CalculatorZilo gives the BLS median and the day-count milestones, Roberin gives decimal years and a day-one count, and AgeCalculatorLab adds another service period for career breaks.
What the guide adds that the three rivals do not is the BLS table, the team-average worked example, the multi-job worked example and the day-one convention, all worked by hand in the guide above.

Frequently Asked Questions
How many years have I worked here?
Enter your start date and select Calculate. The result shows your completed years, months and days of service up to today.
Does the calculator include my start date?
Your start date is day zero, and service builds from there. On your first anniversary you have exactly one year of service.
Can I calculate service up to a leaving date?
Yes. Open “Calculate as of” and enter your last day to see your total service at that date.
Are holidays and leave removed from the weekdays worked?
No. The weekdays figure counts every Monday to Friday in the period. Use the Business Days Calculator to remove specific holidays.
What if I left and came back?
The calculator measures one continuous period. For broken service, calculate each period separately and add them, and check whether your employer counts breaks.
How do I count tenure for a notice period or redundancy?
Use the start date and the leaving date from your contract or payroll records, then check how the relevant law or policy rounds partial years. Many schemes count only complete years of service.
How many years is 1,825 days?
Not exactly 5 years. 1 March 2018 plus 1,825 days is 28 February 2023, one day before the 5-year milestone, because the leap day of 29 February 2020 falls inside the span. Count anniversaries by the calendar date, not by dividing days by 365.
What is the median tenure in the US?
4.1 years in January 2026, according to the US Bureau of Labor Statistics, up from 3.9 years in January 2024. Men had a median of 4.3 years and women 4.0 years. Workers 25 to 34 had a median of 3.0 years, and workers 55 to 64 had 9.6 years.
