How hours to weeks are calculated
A week is 7 days of 24 hours, so divide by 168 to get weeks, or multiply by 168 to go back.
weeks = hours ÷ 168 (1 week = 7 × 24 = 168 hours)
- A week has 7 days and each day has 24 hours, so 1 week is 168 hours.
- Divide the hours by 168 for weeks. To go back, multiply weeks by 168.
- For the split, take out whole weeks of 168 hours, then whole days of 24, and the rest is hours.
- Work weeks divide by the hours you work in a week instead, such as 38 for full time in Australia.
Worked example — 1,000 hours ÷ 168 = 5.9524 weeks. That is 5 weeks, 6 days and 16 hours, or 26.3158 work weeks at 38 hours.

Things to consider
- For timesheets and leave, use the work weeks line, not calendar weeks.
- Australia's standard full-time week is 38 hours. Switch to 40 if your role uses that.
- A 30-day month is 720 hours, which is about 4.29 weeks, not 4.
- For longer spans, the Weeks to Years Converter takes the weeks from here.
