Vernal equinox is actually an astronomy event that is when during spring  both day and night are more longer than 12 hours or it could be more than 13 hours or 15 hours. For example, day and night are different in how they start but lasts more than 14 hours if day is 14 hours then night is too.

Hope this helps ^_^
