About World Mosquito Day

World Mosquito Day is marked on 20 August 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 20 August, and in 2029 on Monday 20 August. 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 August 2027: World Humanitarian Day (19 Aug), Saint Stephen’s Day (Hungary) (20 Aug) and Constitution Day (Hungary) (20 Aug). From this page you can add it to your calendar, get an email before it, share the countdown, or show it full screen.

How we work out the date
