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.
A worked example
Counting 18 months before September 19, 2026 gives March 19, 2025. Calendar months use the last day if the starting day does not exist in the target month.
Try 30 days, 60 days or 90 days from today.
