A fortnight is a unit of time equal to 14 days, or two weeks (1,209,600 seconds).
1 fortnight = 14 d = 2 wk = 336 h = 1,209,600 s.
To convert fortnights to days: multiply by 14. To convert fortnights to weeks: multiply by 2.
Fortnightly pay cycles (common in Australia and UK), rental payment periods, and magazine publication schedules.
In Australia, being paid 'fortnightly' is the most common pay cycle. The FFF system defines speed in furlongs per fortnight.
Americans may be unfamiliar with the term. In US English, 'two weeks' is the standard equivalent.
Fortnight = fourteen nights. In countries where it's common, it's as natural as saying 'week' — just meaning two of them.
The Julian year is a unit of time equal to exactly 365.25 days (31,557,600 seconds), used as a standard in astronomy.
1 Julian year = 365.25 days = 8,766 hours = 31,557,600 seconds exactly.
To convert Julian years to seconds: multiply by 31,557,600. To common years: multiply by 365.25/365.
Defining the light-year, expressing stellar evolutionary timescales, and standardizing astronomical time intervals.
The Julian year is exactly 365.25 days — no exceptions. This simplicity is why astronomers prefer it over the variable Gregorian year.
Confusing the Julian year (365.25 d) with the Julian calendar (which has a specific leap year pattern). They are related but distinct.
When astronomers say 'light-year,' they mean the distance light travels in one Julian year (365.25 days), not a calendar year.
