The solar calendar make no sense , because if you lose track of it, you will have to wait until the next solstice to correct your error.
That is "...if you lose track of the solar year...
Unfortunately what is said here is not true.
God's truth is that the lunar calendar makes no sense,
because it has NO TRACK you can keep of.
Take the prophet's birthday.
It is said that he was born on 12 Rabī‘ al-Awwal 53 BH which was April 23, a spring day.
Peophet Muhammad was born in spring.
But this lunar year Rabī‘ al-Awwal is in winter.
Does that make sense?
Was he born in only spring or all four seasons?
Can a human being be born in all four seasons?
Were YOU born in all four seasons?
