Entering task durations
TIP Project will not allow you to enter a text value for an automatically scheduled task’s
duration, start, or finish value.
Project uses standard values for minutes and hours for durations: 1 minute equals 60
seconds, and 1 hour equals 60 minutes. For the durations of days, weeks, and months, you
can use Project’s defaults (for example, 20 days per month) or set your own values. To do
this, on the File tab, click Options, and in the Project Options dialog box, click Schedule, as
With a setting of 8 hours per day, entering a two-day
task duration (2d) is the same as entering 16 hours (16h).
With a setting of
40 hours per week,
entering a three-week
task duration (3w) is
the same as entering
120 hours (120h).
With a setting of 20 days per month, entering a one-month
task duration (1mo) is the same as entering 160 hours
(8 hours per day × 20 days per month).
The exercises in this chapter use Project’s default values: 8 hours per day, 40 hours per
week, and 20 days per month.
TIP If needed, you can schedule tasks to occur during nonworking as well as working time.
To do this, enter an elapsed duration to a task. You enter elapsed duration by preceding the
duration abbreviation with an “e”. For example, type “1ed” to indicate one full 24-hour day,
or “1ew” to equal seven 24-hour days, or “1em” to equal thirty 24-hour days.
You might use an elapsed duration for a task that goes on around the clock rather than
just during normal working hours. For instance, a construction project might have the
tasks “Pour foundation concrete” and “Remove foundation forms.” If so, you might also
want a task called “Wait for concrete to cure” because you don’t want to remove the forms
