Spring is one of the four seasons, coming after Winter and before Summer. It occurs between the March equinox and the June solstice in the northern hemisphere, while it's between the September equinox and the December solstice in the southern hemisphere.
This season includes the temperature starting to warm up after winter, melting the ice and snow in more temperate and arctic locations. Flowers bloom, and trees start sprouting new green leaves. Easter is also celebrated during this season, mainly occurring in April (though it can also occur at the end of March).
