How this count works
Today is the starting point, so tomorrow is one day from today. Choose “before” to count backward. Calendar days include Saturdays and Sundays.
The weekday alternative skips Saturdays and Sundays but keeps holidays. Today follows the timezone shown, and the answer updates when that date changes.
For example
Counting 21 days after September 19, 2026 gives October 10, 2026. Counting weekdays only gives October 19, 2026.
Try 30 days, 60 days or 90 days from today.
