until your next moment
EVERY LIFE HAS ITS OWN CONSTELLATION
Your life is full of
extraordinary
moments.
Your 10,000th day. Your 100th full moon.
There’s more to celebrate than birthdays.
01 / THE BEGINNING
Every story starts with a date.
Your birthday, an anniversary, or a day that changed everything.
Your date stays in this browser. When available, shared tab-session storage keeps it across pages and refreshes. Browsers may restore closed sessions. Clear date removes it site-wide; sharing is your choice.
02 / YOUR CONSTELLATION
A life worth celebrating.
—days of your story
—weeks of memories
—months of possibility
And so many
moments still to come.

A note on time, astronomy & accuracy
Calendar days and weeks follow your selected time zone, including daylight saving. Month anniversaries clamp to the final day of shorter months. An anniversary in a skipped clock hour moves forward by the DST gap. An ambiguous clock time uses its earlier occurrence.
When no time is supplied, calculations start at 12:00 noon by default. The default remains distinct from an explicitly entered birth or event time. Calendar and elapsed-time milestones are calculated from that starting clock time; elapsed calculations ignore leap seconds. Entered times have minute precision.
Full moons use Jean Meeus’s Astronomical Algorithms, second edition, chapter 49: mean phase, periodic and planetary corrections, and an Espenak–Meeus ΔT estimate to convert terrestrial time to UTC. These are geocentric phase instants, independent of your location. Expected accuracy is within a few minutes for 1900–2100; allow up to 15 minutes for 2100–2200 because future ΔT is uncertain. No second-level astronomical accuracy is claimed. The starting instant itself is excluded from the full-moon count.
Planetary years multiply mean sidereal periods: Earth 365.256363004, Mars 686.98, Jupiter 4,332.589, Saturn 10,759.22 Earth days. These are approximate symbolic anniversaries, not exact returns to an orbital position. Events beyond 2200 are omitted. No location, account, external API, or tracking is required.
