Latest start date
—
The deadline is treated as the final working day of the required duration.
Calculate the latest start date needed to complete a project by a deadline.
Enter the values requested in each field: Project deadline; Working days required; Working days; Mon; Tue; Wed; Thu; Fri; Sat; Sun; Holidays (optional). Keep time units, work calendars, and currency amounts consistent, and follow any field notes and validation messages.
The schedule result estimates a project or task date, duration, working-day count, milestone, or schedule flexibility from the task and calendar values entered. Check the start/end-date convention, workweek, holidays, dependencies, and whether the end date is inclusive.
Use this to plan a project schedule or check a target date. Update dependencies and calendars when plans change; actual delivery can be affected by resource constraints, delays, and work that is not represented in the inputs.
