Below is a month between dates calculator. Enter a start date and an end date and we'll return the number of months and days separating them - plus total days, weeks, and years.
Months between dates calculator
Using the month calculator
To compute the distance in months between two dates:
- Start/End Date: Enter any two dates - the calculator handles them in any order.
- Today Button: Click Today to instantly set either date to the current date.
- Auto-Calculate: Results update instantly as you change dates, with no need to smash a button
The main result shows months and remaining days. The secondary line shows total days, weeks, and decimal years.
I also built a months from now and months ago tool, if this one isn't doing it for you.
Why does a year difference show less than twelve months?
The calculator does not count the final day in the time-frame. That is, it counts the day of the first date but not the ending date.
To get around this, bump the date by one in the end. For example, June 1, 2000 to June 1, 2001 is less than twelve months. However, June 1, 2000 to June 2, 2001 is 12 months.
How do you use the month calculator?
The month difference calculator can be used much like the day difference calculator or week difference calculator. Use it to figure out the timespan that two events or frames overlapped.
