Decennials Calculator
(Planetary Decades)

Traditional time-lord method

This method divides the life into 7 different periods, each lasting 10 years and 9 months. Each of these is governed by one of the 7 planets.
  • The first period starts with the sect light, Sun for diurnal charts, Moon for nocturnal.
  • Following periods/time-lords continue by the next planets after the sect light, going in zodiacal order.
  • Each period is divided into 7 sub-periods. The first sub-period belongs to the same planet as the entire decade. The order of the sub-periods is determined in the same way as the main periods.
  • Optional:
  • Start from Sect Light, Apheta or any other planet
  • Calendar (1 year ~ 360 or 365.25 days)
  • L3 & L4 sub-periods
