About this calculator
Weeks are a convenient unit for planning but an awkward one for arithmetic, because they do not divide evenly into months or years. Converting to days or hours first makes the sums straightforward.

Frequently asked questions
Why does converting weeks to months use 30.44 days?
The converter uses an average month of 30.4375 days and year of 365.2425 days, so months and years are not fixed calendar intervals here. The working-days output is weeks multiplied by five (Monday–Friday) and does not account for public holidays or local work schedules.
