How the Countdown Calculator (Days Until a Date) works
The count is the number of days from the starting date to the event date, so the day before the event shows 1. Hours assume whole days from midnight to midnight.
Months are approximate (an average month is 30.44 days). For exact business days use the working days calculator, which handles weekends and holidays.
