चैत्रवैशाखमासयोः वसन्तर्तुः । वृक्षाः कुसुमिताः भवन्ति । कोकिलाः कूजन्ति । मधुपाः मधु पिबन्ति । उपवनानि शोभन्ते ।

Spring, also known as springtime, is one of the four temperate seasons, succeeding winter and preceding summer. There are various technical definitions of spring, but local usage of the term varies according to local climate, cultures and customs. When it is spring in the Northern Hemisphere, it is autumn in the Southern Hemisphere and vice versa. At the spring equinox, days and nights are approximately twelve hours long, with daytime length increasing and nighttime length decreasing as the season progresses until the Summer Solstice in June and December.
