week

Timeexact by definition

The week is exactly 7 days, that is 604,800 seconds. The factor is exact by definition given the 86,400-second day. Unlike the day, month and year, the week has no astronomical basis and is a purely social division.

Watch out: A week is exact only in terms of nominal days. Across a daylight-saving transition, a calendar week in local time is 604,800 s plus or minus one hour, which matters to scheduling and billing code.
