The years · 4 of 60
丁卯 — Dīng mǎo. Fire above, the Rabbit beneath.
In BaZi the year turns at Li Chun (立春), the solar term that opens spring, computed from the sun's position rather than the calendar's round number. The Fire Rabbit year runs from 4 February 1987 to 3 February 1988. Born in January or early February 1987? Your year animal is almost certainly the one before — check 1986. Many sites get this wrong by assuming 1 January; the date above is computed, and the engine that computed it also resolves the timezone your birthplace was actually keeping.
The Rabbit returns every twelve years (1975, 1999), but the full 丁卯 pillar only every sixty (1927). The same sixty names mark the days as well: there is a 丁卯 day every sixty days.
The year pillar is the part of a chart most people know, and the part that says least. Compute all four pillars, in your browser, with nothing sent anywhere.
