4-on-4-off Holiday Entitlement Calculator

Based on the default pattern below, a typical entitlement is 19.6 days. Adjust the inputs for your exact figure.

19.6 days

How it's worked out

7 × (4 on ÷ 8 cycle) = 3.5 avg days/week × 5.6 weeks = 19.6 days

Audit note

Rotational entitlement is averaged across the full on/off cycle, then multiplied by 5.6 weeks and capped at 28 days. For 12-hour shifts, track leave in hours rather than days to stay accurate.

Stop tracking this by hand

Tempry keeps every employee's holiday and PTO balance accurate automatically, with requests and approvals built right into Slack — no spreadsheets, no re-doing this maths every time someone's pattern changes.

How this calculation works

Rotating rosters, compressed weeks and fortnight patterns don't map neatly onto a Monday-to-Friday week. These calculators average your real days worked across the cycle before applying the 5.6-week multiplier.

Worked example

7 × (4 on ÷ 8 cycle) = 3.5 avg days/week × 5.6 weeks = 19.6 days

Frequently asked questions

How much holiday on a 4-on-4-off pattern?
Across an eight-day cycle you work four days, averaging 3.5 days a week (7 × 4/8). Multiplied by 5.6 statutory weeks that's 19.6 days of paid holiday a year.
Why average the shifts instead of counting weeks?
A 4-on-4-off cycle doesn't line up with a seven-day week, so counting calendar weeks would be inaccurate. Averaging the days worked across the full cycle gives the true weekly equivalent.
My shifts are 12 hours — should I use hours instead?
For long shifts, measuring entitlement in hours is often clearer. Multiply your average weekly hours by 5.6 to get an hours-based figure you can deduct shift by shift.
