How it works

How to Count Back 100 Years

To find the date 100 years ago, subtract 100 from the year. From September 25, 2026 that gives Saturday, September 25, 1926.

In days that was 36,525, or 5,217 weeks and 6 days. The span contains 25 leap days, which is why a year is not always 365 days.

The day of the month stays the same: the 25th. It was a Saturday, so most offices and banks were closed that day.
