Good to know
Weeks = days between the dates ÷ 7. The whole number is the full weeks and the remainder is the extra days: 299 days = 42 weeks and 5 days.
Decimal weeks (42.71) are handy for spreadsheets and planning. Approximate months use an average month of 30.44 days, so they are a guide, not calendar months.
For school sessions, coaching batches or a 12-week course, enter the first and last day and include the end date.
Questions
How many weeks are there between two dates?
Count the days between them and divide by 7. The calculator shows full weeks plus the days left over.
How many weeks are in a year?
52 weeks and 1 day (52 weeks and 2 days in a leap year).
Should I include the end date?
Include it when the last day is part of the period, such as the last day of a course.
Why do months show decimals?
Months have 28 to 31 days, so weeks-to-months is approximate. For exact months use the date difference calculator.
