Annual Leave Calculator

This annual leave calculator answers the question everyone asks before booking time off: how much leave do I have? Choose the rules that apply to you, type your hours and days a week, the date your leave year started and any leave carried over or already taken, and it shows your balance in days and hours.

It follows the real rules. In Australia, the National Employment Standards give full-time and part-time employees 4 weeks a year based on their ordinary hours, building up from the first day, and 5 weeks for some shiftworkers. In the UK, almost all workers get 5.6 weeks of paid holiday, capped at 28 days, so a 3-day week gets 16.8 days. For UK irregular-hours and part-year workers, holiday builds up at 12.07% of the hours they actually work. If your contract gives a set number of days, use your own figure.

You also see how much leave builds up each week, fortnight and month, and a days-to-hours converter based on your own working day. Each set of rules comes with plain-English notes about public holidays and a link to the official guidance. Everything is worked out in your browser, so nothing you type is sent anywhere.

1. Choose your Leave rules: Australia, Australian shiftworker, UK statutory, UK irregular hours, or your own days a year.
2. Type your Hours a week and Days a week, or tap a preset such as 38 h, 5 days.
3. Set the date your Leave year started and the date to Work it out up to (irregular hours: type the hours worked so far instead).
4. Choose Days or Hours, then type any leave Carried over and Leave taken.
5. Read Leave left, the tiles and how it builds up each pay, then use Copy summary to keep a note.

• Use the hours you are contracted for, not overtime: Australian leave builds up on ordinary hours.
• If your days are different lengths, enter your total weekly hours and days; one day is shown as the average.
• UK employers may count bank holidays inside the 5.6 weeks, so check your contract before adding them on top.
• In Australia, a public holiday during your leave isn’t taken from your balance.
• Awards, agreements and contracts can give more leave than the legal minimum; use the custom option if yours does.
