The spring which began at 6:20 PM EDT on Friday March 20, according to researches it is getting 30 seconds shorter each year due to the movement of the Earth’s axis, which gives half a minute to Summer each year
Earth is tilted at an axis of 23.5 degrees and this is the reason why we see seasons on earth. For the six months of the year northern hemisphere leans slightly towards the sun and for the next 6 months the southern hemisphere slightly leans towards the sun.
Spring occurs with the vernal equinox where the axis of the earth is not near to the sun as in the summer and nor away from the sun as in the winter. So this is the reason why we have equal days and nights in vernal equinox.
Spring has been losing time in the northern hemisphere for the past several years.
Larry Gerstman, an amateur astronomer in New York said that this year the longest season was the summer season with 93.65 days then the spring with 92.76 days, autumn with 89.84 days and winter with 88.99 days.
As the years pass by spring will lose its time to summer, winter will be losing time to autumn.
