Months Between Dates
Find how many months are between two dates — as complete calendar months plus remaining days, with an approximate total.
Count the months between two dates
Complete months plus remaining days
Because months vary from 28 to 31 days, the calculator counts whole calendar months first, then shows the leftover days.
Example: 15 January 2024 to 20 April 2024 is 3 months and 5 days.
Why the total months is approximate
The approximate total uses an average month length of about 30.44 days, so it is useful for rough figures but the complete-months-plus-days breakdown is the exact answer.
