Deadline calculator
Pick a start date and how many working days you have. Get the real due date.
How to use it
- Pick the start date. That is usually today, or the day the work was handed over.
- Type the number of working days to add.
- Keep US federal holidays on, and add any other days off.
- Copy the due date.
How the date is worked out
The calculator starts on the next day and counts forward. It counts only weekdays that are not holidays. When it reaches your number, that is the due date.
Example: start on Friday, November 20, 2026 and add 5 business days. Monday 23, Tuesday 24, Wednesday 25 count. Thursday 26 is Thanksgiving, so skip it. Friday 27 and Monday 30 make five. The due date is Monday, November 30, not Friday 27.
Setting deadlines people can hit
A date is easy to set. A date people can hit takes three more checks:
- Is the work clear? A vague brief adds days of back-and-forth. Write the result, the reader and the must-haves first.
- Who reviews it, and when? Add the review days. Feedback that comes late is the most common cause of a missed date.
- Is there a buffer? Add 10% to 20% for anything new.
Where M-Tracker fits
