The Moon from that day, here for you now.

Waning Crescent

A slender light before the new Moon. Between one ending and the next beginning.

Time has passed. The shape of that day’s Moon can still be found.

How to find the Moon on your birthday

  1. Choose your birth year, month and day, then show your Moon.
  2. Read the phase name and illuminated percentage. A Full Moon appears almost completely lit; a crescent shows a smaller sunlit portion.
  3. Select “Share this Moon” to create an image card for that date.

Does birth time or location change the result?

This date-only calculator uses Astronomy Engine at noon Korea Standard Time (03:00 UTC) on the selected date. It does not calculate the exact sky at your birth time or birthplace. Near a phase transition, a different time on the same date can give a different phase or illumination.
