UK Holiday Entitlement Calculator (Prototype)

Inputs (the 9 questions)

1) Leave year start Leave year end

Use your organisation’s holiday year (e.g., 2026‑01‑01 to 2026‑12‑31). End date should be the last day of the leave year.

2) Full‑time weekly hours

Example: 37.5 for 9–5 Mon–Fri (7.5h/day).

Full‑time days per week

Usually 5. Used to convert days ↔ hours.

3) Full‑time annual leave (contractual) – days

Enter your contractual leave days excluding bank holidays if you handle bank holidays separately.

Typical bank holidays per year – days

Often 8 in England & Wales; adjust to your policy/location.

Bank holiday handling 4) Worker pattern

Patterns A/B use pro‑rated annual entitlement. Pattern C uses accrual per pay period (enter hours worked below).

5) Employee days per week

Employee weekly hours

If the employee’s days vary (pattern B), still enter their usual weekly hours; “days/week” is used mainly for bank holiday pro‑rating and for a days-based display.

6) Employment start date (join date)

Employment end date (leave date, if applicable)

Leave blank if still employed.

7) Any change in working pattern during the leave year? 8) Rounding rule 9) Optional: show statutory minimum check (5.6 weeks)?

Notes: This is a pragmatic prototype, not legal advice. It’s designed to match typical UK HR practice (pro‑rating by FTE and partial‑year service). For complex cases (term‑time only, bespoke bank holiday rules, rolled‑up holiday pay), you’ll likely want policy-specific tweaks.
