Qingming (Clear and Bright)

Qingming is the moment the Sun reaches 15° of apparent ecliptic longitude. It is one of the twelve "Jie" — the BaZi month pillar turns to the month at this instant, and the governing month changes with it.

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 Qingming about 5 hours 49 minutes later each year until a leap day pulls it back. That is the whole reason Qingming 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.
