Leap Month
A compensatory month set in lunisolar calendars to reconcile the difference in length between the synodic month and the tropical year, occurring roughly seven times in nineteen years. The specific leap month is determined by the position of solar terms, and a leap-month flag must be carried explicitly during chart casting to avoid calculation errors.

For those born in a leap month, classical texts differ ambiguously on whether the Life Palace is placed according to the current month or the next month in Zi Wei Dou Shu charting.
A leap month is a compensatory month set in lunisolar calendars to reconcile the difference in length between the synodic month and the tropical year; the lunar synodic month is about 29.53 days, twelve months are about 354 days, roughly 11 days short of the tropical year, and the intercalation rule is roughly seven leap months in nineteen years.
When casting a chart, the leap month flag must be carried explicitly, otherwise the month pillar and all subsequent pillars will go wrong in a chain.
