Worked Example — countdown to a future event, and a past one

154d 12h 18m 19s"Time until your event" for a future date — switches to "Time since your event" automatically once the date passes

This counts every calendar day, including weekends — there's no weekdays-only mode. If you specifically need a workdays-only countdown (excluding Saturdays and Sundays), this calculator doesn't have that option — it always counts every day between now and your target date.
For a pregnancy due date, use the Pregnancy Due Date Calculator instead. This is a general-purpose countdown to any date and time you enter — it doesn't estimate a due date from your last period or conception date the way a pregnancy-specific tool does.
