The years · 54 of 60
丁巳 — Dīng sì. Fire above, the Snake 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 Snake year runs from 3 February 2037 to 3 February 2038. Born in January or early February 2037? Your year animal is almost certainly the one before — check 2036. 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 Snake returns every twelve years (2025), but the full 丁巳 pillar only every sixty (1977). The same sixty names mark the days as well: there is a 丁巳 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.
