How this is calculated
Every calendar day counts, including weekends and public holidays. Today is day zero, so 1 day from today is tomorrow. If you need working days only, the business-day count below excludes Saturdays and Sundays (but not holidays, which vary by country and employer).
For example, counted from Saturday, October 24, 2026, 100 days ago was Thursday, July 16, 2026, 100 days earlier.
