Moon on August 21, 2026
This shows the Moon phase on “August 21” for the selected year — by default the nearest upcoming one. Pick another year with the selector above the timer and the phase updates: the ~29.5-day lunar cycle shifts it slightly from year to year.
Our online timer shows exactly how much time is left until August 21, counting down the days, hours, minutes and seconds.
It doesn't matter if you are waiting for August 21 as your birthday, the start of a vacation, the date of an important event, or just out of interest — our counter will help you track the approach of this moment.
For maximum convenience, the timer can be expanded to the full screen, which is ideal for displaying on a large monitor while preparing or waiting.
Works for free and is available on any device
