How Date Difference is Calculated
A Date Difference Calculator works by determining the number of days, months and years between two specified dates. It's a simple but powerful tool for various purposes, such as calculating age, project durations, or the time elapsed between significant events.
Our calculator performs this calculation accurately, taking into account leap years and the varying number of days in each month to provide precise results.
