Forums Computing When is the Spring Equinox? March 2019 Equinox time

John O’Neill


Thank you for your responses.

Jean Meeus gives a time of the spring equinox in 2019 to be 21:59:34 TD in his Astronomical Tables of the Sun, Moon and Planets, 3rd Edition (p.151). Taking Delta T is be 69 s currently and subtracting this value gives 21:58:25 UT. Rounded to the nearest minute this is 21:58 UT.
