• 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
