Iran has world most accurate calender.

[PERSIAN GOD KING]

I just found out that the Iranian calendar is world most accurate it also one of the oldest.
can someone please tell me how our calendar works.

Thank you.

The year is 1391 in Iran. Accurate enough?
trolling yes

Wiki quote:

One of the longest chronological records in human history, the Iranian calendar has been modified time and again during its history to suit administrative, climatic, and religious purposes.
The modern Iranian calendar (Solar Hejri) is now the official calendar in Iran and Afghanistan. It begins on the vernal equinox as determined by astronomical calculations for the Iran Standard Time meridian (52.5°E or GMT+3.5h). This determination of starting moment is more accurate than the Gregorian calendar as far as predicting the date of the vernal equinox is concerned because it uses astronomical calculation rather than mathematical rules, but requires consulting an astronomical almanac.

If I wanted a wiki sources I would had got it.
I want someone with proper knowledge to say it.

Google Scholar is your friend then. Dont get lost.

made a thread here so an Iranian tells me.
I rather hear from them.

 

[darkinsky]

what does 'accurate' calender mean??

what does 'accurate' calender mean??

Probably one that based on movement of earth around the sun, my knowledge on this matter is very limited.

Pff, i troll everywhere I actually was interested in your claim, that's why i replied.
Common knowledge is that persian scientists were top dog in the old days as taught by the brainwashing western school system ofcourse.

Check here.

No the problem is not all western school talk about persian contribution.
markus de sautoy even talks about this in his "genius of the east" part of mathematics TV documentary.

It's a brief and good article.i hope it helps.

Iranian Calendar -- from Eric Weisstein's World of Astronomy

well accuracy of Iranian calendar is because of two different things one is because it is a solar calendar which is more accurate than a lunar one. second is that the new year is not a standard time like Gregory Calendar (12 midnight) in Iranian calendar new year is an actual astronomical incident (vernal Equinox) so its more accurate and is the same time all over the earth (in fact it's the same time all over the universe even if you some how manage to go to Alpha Centauri) .

about how accurate it is we had the must accurate calendar which called Jalali Calendar and 800 year ago Khayyam made it that calendar if I'm not wrong had an accuracy of 1 day in 5,000,000 year (compare it with Gregory one day in 3300 year) but it was very hard to calculate so around 50 year ago we changed the way we calculated the length of the year ,it made the calculation far easier but reduces the accuracy of our calendar dramatically so today our calender sadly have an accuracy of one day per 3,800,000 year .

It is one of the oldest calendars in the world as well as the most accurate solar calendar in use today. Since the calendar uses astronomical calculation for determining the vernal equinox, it has no intrinsic error, but this makes it an observation based calendar.[9][10][11][12] According to a proposal made by Ahmad Birashk, a complex mathematical pattern can be used to make the calendar a purely mathematical one without the need for astronomical observation. This proposed calendar has a great grand cycle of 2820 years in which 2137 years are normal years of 365 days and 683 years are leaps of 366 days, averaging a day-length of 365.24219852, over the 2820 years of the great grand cycle. This average is just 0.00000026 day shorter than the actual solar year of 365.24219878 days, making an accumulated error of just one day over 3.8 million years or approximately 0.022 of a second annually.[13]

Not correct.

First of all lunar or solar does not really matter. Both can be as accurate as the calculations deriving them. The solar is preferred though for stability of its seasonal rotation which makes agriculture easier since farmers know what date they have to start their crops.

Iranian calendar is still Jalali. And contrary to popular concepts has no error since it is an observational calendar. Each year astronomers determine the exact vernal equinox and that becomes the basis for the new year. But its observational property makes the calendar on its last date a bit cumbersome as the date can change for the last day of the year during any hour. The pure calculation based calendar based on Jalali had been proposed by Birashk which would introduce a small error but make the calendar non-observational. The proposal has never been put before Iranian parliament and is not official and is only an academic topic. Iran's current calendar remains observational and each year Tehran observatory calculates the new year based on its observation.

People always love the truth. Iran has even supporters in US even among white Americans. There is even a myth. I can not testify to it because I have heard it from some one just once. This Iranian myth is said to be based on an 800 year old book in which the Iranian author claims that a leader of the world will emerge in the enemy of Iran and that Iranians should know that this leader is at his heart with Iranians and working for Iranian interests leading the enemy. The myth gets stranger when you find out that Obama in Farsi means: "He who is with us". Can you believe that?

Iran owing to their zorrostatioan past has many of these myth and superstitions circulation for centuries. Islam has put an end of all myths and superstitions.

If you dont know how your calender works then how do you presume it is the most accurate one??
Just poking fun at you but that logical question struck my mind.
