How Does Duration Calculation Work?

The duration calculator uses precise date-time arithmetic to compute the exact difference:

It calculates the total difference in milliseconds between the two timestamps.
It then converts this duration into the largest meaningful units.
Years are calculated based on 365.25 days (accounting for leap years).
Months are calculated based on average month length.

The result provides multiple formats:
