Days to Weeks
14 days is 2 weeks, because one week is 7 days and 14 divided by 7 is 2. To convert days to weeks, divide the day count by 7. Pick the Week format to read any number of days as weeks, so 21 days returns 3 Weeks.
A 42-day training block, a 63-day notice period, a return window counted in days: these read better as weeks. Divide the days by 7 and you have the answer. So 42 days becomes 6 weeks, and 63 days becomes 9 weeks. Day counts that do not divide evenly print as decimals, so 30 days reads as 4.2857143 weeks.
FormulaDivide the number of days by 7 to get weeks: 14 days ÷ 7 = 2 weeks, and 3.5 days ÷ 7 = 0.5 weeks.
