Deadline Calculator
Calculate a target deadline date from a start date and number of days.
Tool
How it works
Pick a start date and day count, then optionally exclude weekends.
When weekend exclusion is on, only weekdays count toward the total.
All calculations run locally in your browser and are deterministic.
Examples
A 10-day task starting Monday ends two calendar weeks later when weekends are excluded.
Turning off weekend exclusion gives pure calendar-day deadlines.
