Find out the exact months and days between two given dates by utilizing this simple month calculator. No signup or registration is required to perform the calculation.

The calculation of the months and days is not as simple as it looks because all months do not have the same number of days, Some of them have 30 days, some have 31 days and the month of February has 28 days and 29 in a leap year.

By using an online monthly calculator from date you will just be required to provide both dates and it will perform the whole for you and will deliver accurate results effortlessly.

A leap year is a calendar year and there is no difference between the leap year and the normal year except the one that the leap year has one extra day in the month of February.

A leap year has 366 days. Approximately, it takes 365.25 days for the Earth to orbit the sun. We round it to 365 and to add the missing partial part, one whole day is added every four years to the calendar.

Let’s see the following formula to calculate number of months:

For calculating the difference in years:

Year Diff = Y2 – Y1

Now calculate the age difference in months:

MonthDiff = M2 − M1 + 12 × YearDiff

Calculate the difference in days:

DayDiff = D2 – D1

If DayDiff < 0, adjust MonthDiff by subtracting 1 and calculate the number of days in

the previous month, then add that number to DayDiff.

If it seems difficult then, simply go for a month calculator from date. It will let you count months and determine the time between two dates by just making a couple of clicks.
