About the week and the hour

The week

The week (wk) equals exactly 7 days, or 604,800 seconds. It is universally used as a planning unit across cultures even though it has no astronomical basis — its origin is religious and cultural, traced back to ancient Babylonian, Jewish, and Roman traditions.

The hour

The hour (h) equals exactly 3,600 seconds, or 60 minutes. It is the standard unit for daily scheduling, employment, and short-distance travel time. Like the minute, it is accepted for use with the SI but is not strictly part of the SI system.
