World Manta Day is coming up.

About World Manta Day

World Manta Day is marked on 17 September each year. It’s one of the environmental days listed on Wikipedia.

In 2027 it falls on a Friday; in 2028 it’s on Sunday 17 September, and in 2029 on Monday 17 September. Because it’s a Friday this time, wherever it’s a day off it makes a long weekend of at least three days. Also in September 2027: World Patient Safety Day (17 Sep), National Apple Dumpling Day (17 Sep) and Engineers’ Day (Canada) (17 Sep). From this page you can add it to your calendar, get an email before it, share the countdown, or show it full screen.
