"How long have I worked here?" sounds simple, but the answer changes depending on whether you mean a work anniversary, a vacation-accrual tier, or FMLA eligibility. A precise, date-based method beats counting 365-day years.
Practical Steps to Calculate Tenure
- Get your exact hire date from your records (offer letter, first pay stub). This is your start date.
- Pick the end date — today, your next anniversary, or your last day.
- Choose inclusive vs. exclusive counting. Our Days Between Dates tool counts exclusive of the end date (it measures the gap). For "years of service" many employers count inclusive — the hire anniversary itself marks a completed year.
- Account for leap years. A 365-day approximation undercounts across a leap day. Use a date-based calculator (or our Age Calculator) that lands on the exact month/day.
- Read the result as Y/M/D for precision — e.g., "3 years, 7 months, 12 days" — rather than a single rounded number.
A Real Rule Tied to Tenure: FMLA Eligibility
The federal Family and Medical Leave Act (FMLA) uses employment length as a gate. To be an "eligible employee" you must have:
- Worked for your employer for at least 12 months (they need not be consecutive),
- Logged at least 1,250 hours of service in the 12 months before leave starts, and
- Worked at a site where the employer has 50 or more employees within 75 miles.
Note that "12 months" means 52 weeks of employment, not 365 days — part-time and seasonal weeks count toward the 12 months. (U.S. Department of Labor, 29 CFR §825.110.)
Why Exact Tenure Matters
Many benefit tiers (vacation accrual, tenure bonuses) key off the hire anniversary at 1 / 3 / 5 / 10 years. A one-month rounding error can shift you into the wrong tier, so use exact date math rather than "years ÷ 365."
