To offset the equinoxes at 0 deg. For example the vernal equinox is the 81st day of the year. 284+81=365. 360/365*365=360 and sin of 360 is 0. 23,45*0 is 0 so at the equinox the sun’s declination is 0 degrees (equator)
@@CHANNEL4WERNER this formula is inaccurate for a bunch of other reasons. The suns apparent movement between the tropics in time is not a perfect sine wave anyway because of the different orbital speeds throughout the year. So there’s that for example. The 365.25 vs 365 is the least of its concerns :)

Thank You Faizan Sir for sharing this video to us
Thanks for liking 😊
God bless your very much
Thanks a lot it's really helpful for me
Yeah...me too
How to find the azimuth of south direction on solar survey...?
Tell us about the hour angle
Will provide animated video on the same soon..

Welcome Shriya
why 284 added?

@@marekmiszczak3266 Then why is the fraction not added? 365.25 isn't it? This formula is inaccurate.
