DURATION
The DURATION function combines separate values for weeks, days, hours, minutes,
seconds, and milliseconds and returns a duration value.
DURATION(weeks, days, hours, minutes, seconds, milliseconds)
 weeks: A value representing the number of weeks. weeks is a number value.
 days: An optional value representing the number of days. days is a number value.
 hours: An optional value representing the number of hours. hours is a number value.
 minutes: An optional value representing the number of minutes. minutes is a
number value.
 seconds: An optional value representing the number of seconds. seconds is a
number value.
 milliseconds: An optional value representing the number of milliseconds.
milliseconds is a number value.
Usage Notes
An argument that is 0 can be omitted, but the comma must be included if later Â
values are included. For example, =DURATION(, ,12, 3) would return a duration value
of 12h 3m (12 hours and 3 minutes).
Negative values are permitted. For example, =DURATION(0, 2, -24) would return a Â
duration of 1 day (2 days minus 24 hours).
Examples
=DURATION(1) returns 1w (1 week).
=DURATION(,,1) returns 1h (1 hour).
=DURATION(1.5) returns 1w 3d 12h (1 week, 3 days, 12 hours or 1.5 weeks).
=DURATION(3, 2, 7, 10, 15.3505) returns 3w 2d 7h 10m 15s 350ms (3 weeks, 2 days, 7 hours, 10 minutes,
15 seconds, 350 milliseconds).
