Is the year 13 months?

[sooroor]

We know that moon is perfect in the 14th day of the month before that 13 days and after it 13 days be it 27 + the day in the month when the moon disappears so 28 days

meaning the moon month is 28 days

28×12 = 336 : far away from the year we know

So let's multiply it per 13!

28×13=364 days in the year which is admittable!

Let's suppose months are based on the moon and year on the sun

Hypothesis:

Sun year = 364 days =13 months =52 weeks (exacly)

Season = 91 days = 3 months and one week(exacly)

Month=4 weeks (exacly)

This is the true and simple and clear calculation of the year and we need to clean our messiness as humans life can't go on if we base it on wrongness.

Only approximately. It is actually 29 days, 12 hours, 44 minutes and 3 seconds for the Moon to complete one lunar month.

Sun year = 364 days =13 months =52 weeks (exacly)

 

Except that is not exact. The solar year is 365 days 5 hours 48 minutes 46 seconds.

So we must ignore your proposal.

So basically you just proposed the Chinese Yang calendar.

[Strange]

Not quite.

 

By the middle of the 2nd millennium BC, Chinese observers had concluded that the solar year was pretty nearly 365.25 days long.

...

Each cycle of the moon is very close to 29.5 days long. To accommodate the half day, some Chinese months are 29 days long and some 30 days long.

...

In other words, there are (365.25 ÷ 29.5 = ) 12.3813559322 lunar months per year. That is not a very felicitous number ...

The modern version of the calendar includes intercalary lunar months to keep things in step.

Also months 9-12 are erroneously named and we're using a lame 60-base system for time keeping. There are so many things that are wrong with the current time measuring.

 

But the fact is that lunar calendars have been used by many cultures throughout the early history and are still being used now, mostly for religious purposes. The biggest problem with lunar calendar is that it's not linked to seasons and depending on how you set it up it will drift around 10 days each year.
