Walk/Bike to School Day

May 05, 2021 to May 06, 2021

Mark your calendar for National Bike to School Day on May 5, 2021, and get ready to bring attention to the value and joy of safe walking and rolling!

The first-ever National Bike to School Day took place on May 9, 2012, in coordination with the League of American Bicyclists’ National Bike Month. Almost 1,000 local events in 49 states and the District of Columbia joined together to encourage children to safely bicycle or walk to school.

The event builds on the popularity of Walk to School Day, which is celebrated across the country – and the world – each October. Many communities and schools have been holding spring walk and bicycle to school events for years. National Bike to School Day provides an opportunity for schools across the country to join together to celebrate and to build off of the energy of National Bike Month.

World Bee Day

May 20, 2021 - 12:00 am to 11:59 pm

Bee engaged!

To raise awareness of the importance of pollinators, the threats they face and their contribution to sustainable development, the UN designated 20 May as World Bee Day.

The goal is to strengthen measures aimed at protecting bees and other pollinators, which would significantly contribute to solving problems related to the global food supply and eliminate hunger in developing countries.

We all depend on pollinators and it is, therefore, crucial to monitor their decline and halt the loss of biodiversity.
