Πώς να υπολογίσετε το Date Difference
Τι είναι το Date Difference;
A date difference calculator computes the exact number of days, weeks, months, and years between two calendar dates. Useful for countdown timers, age calculations, contract duration, and deadline tracking. Accounting for leap years makes this non-trivial: 2000 had 366 days, most centuries do not.
