I got a message on Christmas stating that there was a time when Christmas and Makar Sankranti used to be celebrated on their website same day.
After a quick web search, I found that Sun takes 20mins extra in it's cycle each year which means it would take 1day extra after 72 years.
Hence, Makar Sankranti would shift ahead by 1day after 72 years (or after a century). Makar Sankranti celebration on 14th January is going to complete that time and soon it would shift to 15th January permanently for 70-100 years and then would move to 16th January after a century and so on.
To testify this, I quickly checked Makar Shankranti dates on https://amp.drikpanchang.com/sankranti/makar-sankranti-date-time.html?year=YYYY website and here are the results:
year=0519 : 25dec
year=1019 : 01jan
year=1519 : 08jan
year=2019 : 15jan
year=2519 : 22jan
year=3019 : 29jan
year=9019 : 21apr
So my question is Is it true that two thousand years ago Makar Sankranti used to be celebrated in December and would be celebrated in April after seven thousand years?
It might be difficult for future dates but atleast is it true that in 1519, Makara Sankranti was celebrated on 08jan?
