Annual Leave Calculator (Ireland)
Estimate statutory annual leave under Irish rules by entering your work pattern below.
This tool follows the common statutory methods: 4 working weeks (if 1,365+ hours), 1/3 of a working week per qualifying month, or 8% of hours worked (up to a max of 4 working weeks).
How annual leave works in Ireland
If you are searching for an annual leave calculator Ireland, the key idea is simple: your legal minimum annual leave is calculated using statutory methods, and you get the most favourable result.
Under Irish working time rules, annual leave is typically calculated using one of the following:
- 4 working weeks in a leave year (where you worked at least 1,365 hours),
- 1/3 of a working week per month where you worked at least 117 hours,
- 8% of hours worked in the leave year, subject to a maximum of 4 working weeks.
The practical outcome is that full-time and part-time employees can both build up annual leave in proportion to their working pattern.
How to use this annual leave calculator Ireland tool
1) Enter your hours worked
Add up your total hours worked in the leave year (or your best current estimate if the year is still in progress).
2) Enter qualifying months
For the monthly method, count how many months you worked at least 117 hours.
3) Enter your weekly schedule
Add your typical working days per week and hours per day. This lets the calculator convert your entitlement into weeks, days, and hours.
4) Compare methods automatically
The calculator shows each method and returns the highest statutory entitlement.
Example scenarios
Full-time employee
A worker doing 5 days per week and 8 hours per day, with 1,365+ annual hours, generally reaches the 4-week statutory ceiling.
Part-time employee
If someone works fewer days or shorter shifts, the entitlement still applies proportionally. The result may be lower in days, but still accurate to their schedule.
Annual leave vs public holidays
Annual leave and public holiday entitlement are different rights. This page calculates annual leave only. Public holiday calculations depend on your work pattern and whether you normally work on the day concerned.
Important notes for employees and employers
- Employment contracts can offer more leave than statutory minimums.
- Keep accurate records of hours worked and leave taken.
- If in doubt, seek guidance from HR, payroll, or official workplace relations resources.
- This calculator is an estimate tool and not legal advice.
