There are two equinoxes every year – in March and September –

when the sun shines directly on the equator and the length of day and night is nearly equal.

The equinox in March is also known as the "spring equinox" in the northern hemisphere.

Here are the photos of the spring equinox.

The spring equinox marks the start of spring and has long been celebrated as a time of rebirth.

Many cultures and religions celebrate or observe holidays and festivals around the March equinox,

Ukrainians have celebrated Dazhbozhych's Velykden (a big day, bigger than night)

on the first Sunday after the spring equinox.

Here are some photos of Dazhbozhych's Velykden 2013 not far from the gymnasium.

The Sun plays on this day. Though winter does not want to surrender, the Sun is very warm.
