Formula / Working

The calculation for the number of months between two dates depends on the year and month of each date. The general formula is: Months Between Dates=(Year2−Year1)×12+(Month2−Month1)\text{Months Between Dates} = (\text{Year}_2 - \text{Year}_1) \times 12 + (\text{Month}_2 - \text{Month}_1)Months Between Dates=(Year2−Year1)×12+(Month2−Month1)

Where:

Year1 and Month1 are the starting date's year and month
Year2 and Month2 are the ending date's year and month

Some calculators also account for days to provide fractional months or adjust for partial months if the end day is before the start day.
