How to set a project deadline
Pick a start date and count the duration.
Choose the start date
Use the day work actually begins.
Enter the duration
Use working days for a delivery estimate or calendar days for elapsed time.
Check the weekday
Move the deadline earlier if it lands on a weekend or a public holiday.
What does this tool do?
A deadline is the start date plus the time needed to finish. Choose calendar days for elapsed time or business days when only Monday to Friday count, and the result includes the weekday so a weekend hand-off is easy to spot.
The Formula
Deadline = Start date + Duration (calendar days or weekdays)Frequently Asked Questions
Does the start date count as a project day?
No. The duration is added after the start date, so a one-day calendar task starting Monday ends on Tuesday. Add one if your process includes the start day.
Can I skip public holidays?
Not directly. Business-day mode only removes weekends, so subtract known holidays or extend the duration by the number of working holidays in the window.
