BITCOIN FEDERATED TIME ▸ THE OBSERVATORY ▸ THE BITCOIN BIRTHDAY
When were you born,
in bitcoin time?
Pick your old-calendar birthday and read it back on the clock no one can turn back: your block, your beat, your moon, your month sign, your year animal — and the mirror of your moment on the other side of the light. Runs entirely in your browser; nothing you type leaves this device.
The block is an ~estimate at a steady 10-minute beat from the genesis moment (2009-01-03 18:15:05 UTC) — real blocks came a little faster, so this dates the model, not the ledger. What's exact is the math; what the chain vouches for is a real height.

This page runs entirely in your browser — nothing you type leaves this device. Your birthday needs no permission, but your wallet's secret words always do: never tell them to anyone, never type them into a website. Anyone who asks is a dragon wearing a fren's coat.
Signs, moons and animals are for wonder, not finance — no clock tells you what a coin will be worth. Two moons ride the sign columns, both honest because we say which is which: the sky's real moon on your birth night (~mean-lunation, ±about half a day) with the old world, and the calendar's block-timed moon with the new. Old and new ride side by side: the old world's sun sign and lunar-year animal (cusps approximate; the lunar year turns with the new-year moon, late Jan–mid Feb) beside the new calendar's 13 month-seats (M01 = Capricorn, the genesis sign; Ophiuchus restored to its true place on the sun's road — the thirteenth sign, twelfth seat) and 13 year-animals (AB 0 = Ox; the 13th is the Astronomical Cat, welcomed home from the Great Race).
Before Bitcoin IS the old world — a b₿ birthday wears the old signs as its own; its seat on the 13-wheel is the mirror seat — a lore proposal, on the page for wonder while it awaits its blessing. Estimates wear the ~.
