In ancient Latvia, Bindus Diena was a festival observed on March 18, the day after Kustonu Diena. It was later named Binduli Diena, in honor of St. Benedict. It was associated primarily with insects.

Everybody must be awake before the sunrise. Water must not be poured inside barns. The backs of the cows, and the barns' ceilings, must be washed. Bears were believed to wake up on this day, but then fall back asleep. Bringing firewood in on this day will bring snakes with you. Rushes, twigs and straw will also attract snakes. Potatoes and cabbages can not be planted on this day.
