The astronomical spring begins on 20 March 2017 and ends on 20 June 2017. The astronomical calendar determines the seasons due to the 23.5 degree tilt of the Earth's rotational axis in relation to its orbit around the sun. Both equinoxes and solstices are related to the Earth's orbit around the sun.

When does spring officially start? How do we define the seasons? It depends on whether you are referring to the astronomical or meteorological spring. When we talk about the beginning of winter or any other season, we are usually talking about the day in our calendars that mark this date. This refers to the astronomical seasons which are a result of the Earth's axis and orbit around the sun.

The spring equinox, the point at which the length of day and night is equal, falls on 20th March this year and usually marks the beginning of spring. However, the date of the spring equinox varies slightly from year to year. It can fall as early as 19th March or as late as 21st. Since spring (and other seasons) can begin on different days each year, it can be hard to compare seasons from year to year. To standardise the length and start of the seasons, in meteorology, the 12 months of the year have been split up into four, 3-month periods. Therefore, meteorological spring begins on 1 March every year and ends on 31 May, allowing weather forecasters to accurately make comparisons between different springs.

Many folks assume the first day of spring in the Northern Hemisphere — also known as the vernal equinox — has always come on March 21. But this year seems to be an exception, for in 2013 the first day of spring comes on Wednesday, March 20 at 11:02 UT, or 7:02 a.m. EDT/4:02 a.m. PDT. Now this doesn't seem right.
