Calculate how many full months are between two dates, plus any remaining days.
Months are the right unit for a lot of financial and planning calculations — subscription durations, tenancy terms, loan periods, subscription costs, and project phases often work better in months than days or years.
Enter two dates and this calculator returns the exact number of complete months between them, plus the remaining days. It correctly handles the varying lengths of different months rather than assuming 30 days each.
Useful for calculating how long you've been in a job, how long until a lease ends, how many months a fixed-rate period runs, or how long a subscription has been active.
The calculator counts whole calendar months (e.g. January 15 to March 15 is exactly 2 months) and then adds the remaining days. It doesn't assume 30-day months.
You'll get 0 months and the number of days between the two dates.
Yes — enter the lease start date and end date to get the exact duration in months and days. This is useful for confirming the term matches what's written in the agreement.
