1) Does the employee work irregular hours or for part of the year?

Irregular hours: hours in each pay period often change. Part-year: there are whole weeks in the leave year with no work and no pay.

Supported Work Patterns

  • Regular workers: days worked per week, hours per week, compressed hours, annualised hours, shifts
  • All period types: full-year, starting part-way, leaving part-way, starting and leaving part-way
  • Irregular and part-year workers: post-1 April 2024 pay-period accrual route (12.07%)
  • Legacy support: leave years before 1 April 2024
  • Built-in validation: date ranges, shift patterns, and maximum statutory boundaries

Frequently Asked Questions

Why does the tool ask for leave year start dates?

Because pro-rating depends on where employment dates sit inside the leave year range, including leap-year handling for date boundaries.

Why are some results in days, some in hours, weeks, or shifts?

The unit follows the entitlement basis from the contract. The calculator keeps the same unit style used in GOV.UK outcomes for each route.

Can employers give more leave than this result?

Yes. Statutory entitlement is the legal minimum. Employment contracts can provide additional paid leave beyond the statutory figure.
