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.
