Measurement of time
The Pavhaki wiki makes heavy use of its own system of time which must be understood in order to make sense of the history in this wiki. The core principles are as follows:
- A biennial is 2 Pavalan years, which are 0.51 Earth years each. A biennial is thus equivalent to 1.02 Earth years.
- There are 168 local days per local year, and 336 local days in every biennial.
- Months are generally understood to mean periods of 30 days unless specified.
- Weeks are generally understood to mean periods of 6-8 days unless specified.
- As defined by the Nautical Charter, a week is the basic division of time and is eight days long.
- A day is generally understood to mean the length of a Pavalan day, which is equivalent to 26.5 Earth hours.
The calendar used on this wiki is the Universal Calendar.
- The shorthand acronym is Y.
- Years are numbered beginning from 0.
- Year zero is considered to be around the start of agriculture.
- There are 168 days in a year, numbered from 0-167.
- Every 7 years a leap day is added.
- In leap years, there are 169 days numbered from 0-168.
- Dates are written YYYYY/DDD
- The 67th day of 15121 would be written 15121/066.
- The leading zeroes are optional.
- Day zero is the spring equinox in the northern hemisphere.
Via the assumption that seasons begin at their equinoxes and solstices:
- Northern Hemisphere:
- Spring is from days 0-41
- Summer is from days 42-83
- Fall is from days 84-125
- Winter is from days 126-167
- Southern Hemisphere:
- Fall is from days 0-41
- Winter is from days 42-83
- Spring is from days 84-125
- Summer is from days 126-167
