The spring season often brings warmer temperatures and new growth, and is celebrated by people around the world with festivals and fairs. Spring is the period of time between the vernal equinox, which falls around March 21 each year, and the summer solstice, which takes place every year on June 21. As the spring season progresses, days and nights become milder, flowers and plants bloom, and days become longer.
In many places, the reprieve that warm spring days offer from the bitter cold days of winter is cause for celebration. In Europe spring is associated with the beginning of the crop production season, as crops begin to blossom. Animals also end their hibernation periods and along with birds, often embark on migrations.
