Xiaoxue (Minor Snow)
Xiaoxue is the moment the Sun reaches 240° of apparent ecliptic longitude. It is one of the twelve "Qi", which do not move the BaZi month boundary.

Why it is not the same date every year
A tropical year runs about 365.2422 days while a calendar year is a whole 365 or 366. The leftover quarter-day accumulates, pushing Xiaoxue about 5 hours 49 minutes later each year until a leap day pulls it back. That is the whole reason Xiaoxue lands on different dates across 2020–2035 and drifts within roughly a day: the term itself is perfectly regular — every 15° of longitude — and the wobble belongs to the calendar, not the sky.
