About Week (wk)
Definition
The week is a unit of time equal to 7 days, or 604,800 seconds.
Mathematical Relationship
1 wk = 7 d = 168 h = 10,080 min = 604,800 s. A year has about 52.18 weeks.
Conversion Formula

Practical Applications
Pay periods (biweekly), pregnancy tracking (40 weeks), sprint cycles in agile development, and workout schedules.
Interesting Facts
The seven-day week has no astronomical basis — unlike days, months, and years, it's a purely human invention. It has been continuous for thousands of years.
Common Mistakes
Assuming months are exactly 4 weeks — most months are 4.3 weeks (30–31 days). Only February in non-leap years is exactly 4 weeks.
Educational Tips
Days of the week in many languages reflect the seven celestial bodies: Sun-day, Moon-day, Saturn-day, etc.
About Fortnight (fn)
Definition
A fortnight is a unit of time equal to 14 days, or two weeks (1,209,600 seconds).
Mathematical Relationship
1 fortnight = 14 d = 2 wk = 336 h = 1,209,600 s.
Conversion Formula
To convert fortnights to days: multiply by 14. To convert fortnights to weeks: multiply by 2.
Practical Applications
Fortnightly pay cycles (common in Australia and UK), rental payment periods, and magazine publication schedules.
Interesting Facts
In Australia, being paid 'fortnightly' is the most common pay cycle. The FFF system defines speed in furlongs per fortnight.
Common Mistakes
Americans may be unfamiliar with the term. In US English, 'two weeks' is the standard equivalent.
Educational Tips
Fortnight = fourteen nights. In countries where it's common, it's as natural as saying 'week' — just meaning two of them.
