Questions
How many hours are in one week?
168 — seven days of 24 hours each. Every further week adds another 168, so the conversion is a single multiplication.
How many working hours are in a year?
Around 2,080 for a 40-hour week over 52 weeks — not 8,736, which is the elapsed hours of a whole year. After public holidays and leave, most full-time years land between 1,800 and 1,900 hours actually worked.
How do I turn a pile of hours back into weeks?
Divide by 168, or solve the other way here: 500 hours are 2.98 weeks. If those are working hours rather than elapsed hours, divide by your own weekly hours instead.
Does the calculator handle part weeks?
Yes. A quarter week is 42 hours and 1.75 weeks are 294 — decimals work in both directions.
Does daylight saving time change the answer?
No. The conversion assumes every day has 24 hours and ignores clock changes, time zones and leap seconds. For a span that crosses a clock change, work in UTC and convert the endpoints afterwards.
