Calendar dates or elapsed time?
A date difference counts calendar boundaries; elapsed hours compare instants. Choose the date tool for days between events, the age tool for completed years and months, and the hours tool for shifts or timesheets. Decide whether to include the first or last day. For a deadline, choose working days and supply the weekend pattern and holidays that apply to your organization. A holiday calendar from another region can produce a plausible but incorrect due date.
Use the event's date and time zone
Clock readings can repeat or disappear when daylight-saving time changes. Enter the actual dates and named time zone when you need elapsed time across such a change. A fixed UTC offset describes one offset, not a region's seasonal rules. Unix timestamps represent instants; confirm whether your source counts seconds or milliseconds. For recurring meetings, compare more than one date because different regions change their clocks on different schedules.
