How to use this tool
Type any number of weeks, whole or fractional.
The headline result answers the classic question: 168 hours in one week.
All smaller units are shown for planning and scheduling.
Weekdays are shown as 5 per week — an approximation that ignores holidays.
Formula & worked example
1 week = 7 days = 168 hours = 10,080 minutes = 604,800 seconds. 2 weeks = 336 hours. 52 weeks = 8,736 hours (a 365-day year is 8,760 hours, so 52 weeks is one day short).
Limitations — read this before you rely on it
A calendar week is 7 × 24 hours in this calculator. Across a daylight-saving clock change, a local week can be 167 or 169 hours on the clock, and a working week depends on holidays and schedules — the weekday figure is an approximation.
