To calculate how long you've worked somewhere, subtract your start date from today (or your end date if you've left). The result is typically expressed in years, months, and days.

Why Employment Duration Matters
Your length of service affects:
- Annual leave entitlement: Many companies increase leave with tenure
- Redundancy pay: Often calculated based on years of service
- Pension contributions: Vesting periods require minimum service
- Notice periods: May increase after certain tenure thresholds
- Reference checks: Employment dates are commonly verified
How to Count Years, Months, and Days
The calculation works like this:
- Count complete years from your start date
- Count remaining complete months
- Count remaining days
For example, if you started on March 15, 2020 and today is January 10, 2026:
- 5 complete years (March 15, 2020 to March 15, 2025)
- 9 complete months (March 15 to December 15, 2025)
- 26 days (December 15 to January 10)
- Total: 5 years, 9 months, 26 days
Breaks in Employment
If you had breaks in employment:
- Continuous service: Some breaks preserve continuity (maternity leave, sick leave)
- Broken service: Other breaks reset the clock (resignation and rehire)
- Statutory rules: Laws define which breaks count in which countries
Check your local employment law or contract for specifics.
For Your CV/Resume
When listing employment duration on a CV:
- Use month and year format (e.g., "March 2020 - January 2026")
- Be accurate—employers often verify dates
- Include the total if it's impressive (e.g., "5+ years")
