Earthquake Remembrance Day in Turkmenistan is to honor the victims of the devastating 1948 Ashgabat earthquake. This national day of mourning commemorates one of the deadliest natural disasters in the country's history.

Vernal Equinox Day is celebrated in Japan marking the moment when day and night are nearly equal in length. It symbolizes balance, renewal, and the arrival of spring. Originally a Shinto and Buddhist observance honoring nature and ancestors, it became a national holiday in 1948. Today, people visit family graves, enjoy the beauty of blooming flowers, and reflect on harmony between humans and nature.
