Tips & common mistakes

Quick tips

  • 1 week = 7 days = 168 hours.
  • ISO 8601 week numbering standardises "Week 01 of Year" internationally.
  • Some cultures start week on Sunday, others on Monday — check locale.

Avoid these

  • Assuming week starts on Sunday in Europe — most of Europe starts Monday.
  • Mixing fiscal weeks (e.g. 4-4-5 accounting) with calendar weeks.
  • Using "week" in science without specifying Julian or Gregorian basis — rarely matters but can.
