Working with business days
Date calculations can depend on calendar rules, time zones and whether endpoints are included. A duration in hours is different from a number of calendar days when daylight-saving changes occur.
Common questions
Are all days exactly 24 hours long?
Elapsed time across a daylight-saving transition can differ from a simple calendar-day count. Use the measure relevant to your schedule.
Why can the same timestamp show different dates?
A timestamp represents an instant, while a calendar date is interpreted in a time zone. Near midnight, the same instant can fall on different local dates.
