One of our fave, newish observances is June 3, World Bicycle Day. Hashtag: #worldbicycleday.
In April 2018, the United Nations General Assembly declared June 3 as International World Bicycle Day. Leszek Sibilski led a campaign to promote a UN Resolution for World Bicycle Day, eventually gaining the support of Turkmenistan and 56 other countries.
