Duration Context

Calculating the time between dates is more than just subtracting numbers. Our tool accounts for the Gregorian calendar nuances, including the variable number of days in months (28-31) and the quadrennial leap day. This ensures that a duration of "1 month" is contextually accurate based on the starting month.
