Public holidays in between

Choose a country to list its public holidays in this span.

Holiday lists come from official government sources and cover 2026 to 2028; outside those years only weekends are skipped. The facts above use your device’s time zone and move on at your midnight.

Which weekday 100 days later falls on

100 days is 14 weeks and 2 days. The whole weeks bring you back to the starting weekday and the remaining 2 days move you 2 weekdays on: 100 days from a Monday is a Wednesday.

Depending on the start day, the span holds between 70 and 72 weekdays (Monday to Friday) and 28 to 30 weekend days. Counting forward from Mondays, Tuesdays, Wednesdays and Sundays gives the most weekdays.

The row for today’s weekday is marked. Public holidays do not change the calendar count; they only reduce the working days.

100 days in weeks, months and years

100 days is about 3.3 months on average, but it never equals a whole number of calendar months: 3 months always last 89 to 92 days, so the date is 8 days or more after the same calendar date 3 months on.

A 29 February only matters if it falls inside the span, and then it is simply one more day in the count: 100 days after February 1, 2028 is May 11, 2028, but 100 days after February 1, 2027, with no leap day on the way, is May 12, 2027.

How the count works

Today is day 0 and tomorrow is day 1, so 100 days from today is reached by stepping forward one calendar day 100 times, weekends and holidays included. If you count today as day 1, day 100 is Wednesday, February 10, 2027, one day earlier. The hub explains exclusive and inclusive counting, and the court rule that counts the same way.
