About finance countdowns
Markets run on the calendar, and this page counts down to the dates that move money: the next Bitcoin halving (expected April 2028), the US tax filing deadline every April 15, and landmark market moments like the SpaceX IPO.
Some financial dates are mechanical certainties — the halving is hard-coded into Bitcoin's protocol at block 1,050,000, drifting only with mining speed — while others are fixed by law (Tax Day) or by corporate announcement (IPOs). We badge anything not yet exact and tighten the countdown as the date converges.
Each page explains the mechanics in plain language: why halvings exist and what they have historically meant, what happens if you miss the tax deadline (and how extensions actually work), and the numbers behind record listings. Deadlines are kinder when you can see them coming.
