The days are done, no time to run in 1390; But now there’s fun and lots of sun in 1391

The first day of the New Year 1391 is March 20, but the precise moment spring arrives, Saat-e Tahvil, is the real start of the New Year.  This year that is 1:14:27 a.m., Eastern Time, Tuesday, March 20, and an hour earlier in successive times zones.
