message: I know this not a delibrate action and the intentions are not ill but please take down the illustration where it says to be an illustration of our Prophet Muhammad PBUH because this will unintentionally cause billions of Muslim's emotions being hurt as in our belief associating portraits of our Holy Prophet PBUH is disrespect. 139.135.36.84 (talk) 15:25, 19 March 2023 (UTC)

thread_title:  an error which is causing harm to sentiments of billions muslims. 

message: I've edited the Months section to replace a direct quote from the Astronomical Almanac supplement ("As a result, the cycle of twelve lunar months regresses through the seasons over a period of about 33 [solar] years") with a less ambiguous explanation  ("This causes the Hijri calendar to gain a year against the Gregorian calendar over a period of 33 solar years, though dates themselves do not correspond from cycle to cycle"). This clarifies that the source is referring to the phase difference of the two calendars, not the period after which a given date in one will land on the same date in the other.
I unfortunately have not been able to find a source for what that period is, mostly because I'm not familiar enough with horology to know the best term to use to find one, but hopefully the fact that I'm clearing up a potential misinterpretation of the provided source (and one that can be seen repeated elsewhere on the internet, despite how implausible it becomes once one stops to think about it for more than a moment) means a new source isn't strictly necessary and my edit can stand until someone else can clean up behind me.
OR, but a fun fact all the same: based on the (tabular) Islamic calendar averaging 354.37 days per year and the Georgian averaging 365.2425, period after which the pattern of corresponding dates between the two calendars will repeat would be indicated by the cumulative days' divergence being divisible by the average number of days. I ran out of rows in Excel trying to calculate that, which means it's not below 1,048,577 years. I'm sure there's a way to calculate it, as Abramsky did for the Hebrew calendar's 14.39 billion years - but I'm not a mathematician either, so I'll leave that to some other poor sod!

replies: text: I'm not convinced that you have come up with the right solution here, so I am reverting for now, per WP:BRD. I appreciate the clarity problem but the AAS is more NPOV: it expresses the movement strictly with respect to the seasons and makes no reference to a calendar that may be seen as Christian. (Nitpickingly so, IMO, but technically correct.) Also, I don't see the ambiguity? the AAS doesn't mention dates at all. Can you think of a better way to express it? (I can't!) Meanwhile, rather than a full-on revert, I'll make your text a footnote.  --𝕁𝕄𝔽 (talk) 20:14, 7 April 2023 (UTC)
