Questions tagged [timespan]

An elapsed measurement of time between two events or during which an event, program or a function continues. Also known as a timedelta or a duration.

A timespan is an elapsed measurement of time between two events or during which an event, program or a function continues.

It is also known as a timedelta or a duration in many programming languages.

  • For most intervals of time, this is calculated by:

    EndTime - StartTime

    This works especially well for half-open intervals that are used by time-only ranges, or date+time ranges.

  • However, be careful with date-only ranges. Typically these are expressed using fully-closed intervals, such as Jan 1 to Jan 2 to represent two days. This is calculated by:

    EndDate - StartDate + 1
