How to Use
- In the "Employment history" section, fill in a start date and an end date. If you are still employed there, tick "To date" and today's date is used automatically.
- If you have worked at more than one employer, click "+ Add another period" and keep filling them in; the tool adds every period together.
- Results update in real time, showing cumulative seniority in years, months and days, the total number of days, the equivalent in years, and the matching statutory annual leave entitlement.
- Click "Load sample data" to see how two periods of employment are combined.
Features
- Supports several periods of employment: job changes and gaps in employment can be entered separately and are combined into a total automatically.
- A "To date" checkbox means you do not have to type an end date for your current job; today's date is used instead.
- Reports cumulative seniority three ways: exact years/months/days, total days, and the equivalent number of years.
- Matches your cumulative service against the Regulations on Paid Annual Leave for Employees and shows the statutory entitlement (none below 1 year, 5 days from 1 up to 10 years, 10 days from 10 up to 20 years, 15 days at 20 years and above).
- Pure front-end date arithmetic; nothing you enter is uploaded.

FAQ
How is work seniority calculated, and how does it differ from company tenure?
Work seniority is the total time you have been employed since you started working and can span several employers, while company tenure means continuous service at your current employer only. This tool accepts multiple periods and adds them up, so it calculates cumulative work seniority.
How much statutory paid annual leave am I entitled to?
Under the Regulations on Paid Annual Leave for Employees, employees with at least 1 but less than 10 years of cumulative service get 5 days, those with at least 10 but less than 20 years get 10 days, and those with 20 years or more get 15 days. Employees with less than 1 year of cumulative service get no annual leave that year.
Do I get annual leave with less than a year of service?
Under the national rules, no: employees with less than 1 year of cumulative service are not entitled to paid annual leave that year. Some employers offer better terms internally, so your company's own policy is what actually applies.
What happens to gaps between jobs, for example a few months out of work?
The tool sums the days of the employment periods you enter, so gaps in between are simply not counted. It never fills in or merges across a gap on its own.
