@ Tom Peters: Tom, what do you think? I added the following paragraph:
One may wonder whether the pattern of dates of Easter repeats. As can be verified in a table of the dates, the dates from 1948 to 2047 are the same as for those 152 years later (2100 to 2199). This period of 152 years is one day short of two Calippic cycles, and is a whole number of weeks. Also the dates for 1800 to 1899 are the same as those for 152 years later (1952 to 2051) in all but 11 cases. The epacts differ by 1, as do the dates of the ecclesiastical 14th of Nisan, but usually the next Sunday falls on the same date. It is possible to have the same dates for the 14th of Nisan and on the same day of the week for other intervals, but since the golden number is not the same, this situation lasts for less than 19 years at a time. For example, the 100-year period 1980-2079 is almost repeated 220 years later (2200-2299), but with six cases that don't agree. An interval of 18,000 years achieves this in some cases
Footnote (which I can't seem to put here in the talk page): It is easy to verify that this occurs if the interval contains 58 lunar corrections and the golden number of the first of the two years in question is less than 13, or if there are 57 lunar corrections and the first golden number is greater than 12. In either case, these cancel out the 135 solar corrections.
and is also a whole number of 400-year Gregorian cycles, but again the golden number will be different, so the pattern does not repeat exactly.
Five minutes later Jc3s5h reverted it, saying that it's a "wall of text" that doesn't answer the question I asked at the beginning -- whether the pattern repeats, and he says it repeats in 5.7 million years. Well of course, we all know that. But does that justify reverting my edit? The question I mean is whether the pattern repeats for a while, like a century, and the answer is yes. I think it's quite interesting, and should be in the article. Eric Kvaalen ( talk) 19:25, 10 September 2023 (UTC)
I suggest that those of you who don't find it interesting stop reading it and go find something else to doThat could be addressed to our readership. This article isn't a personal blog existing for your self-indulgence. DeCausa ( talk) 19:27, 11 September 2023 (UTC)
I hope it's clear from what I wrote yesterday that this is not a case of pareidolia. I have a question for Caligula, Claudius, and Nero: You say what I wrote is not interesting, and I suppose you are concerned for the disk space of Wikimedia. What if I find three μαρτῠ́ρους who will attest to finding that it is interesting? Is it still you who get to decide? Eric Kvaalen ( talk) 07:09, 12 September 2023 (UTC)
Astrolynx added a citation needed template to the caption for an image of a table. I have a hard time reading the table and can't tell if it supports what is stated in the caption. If the table says what the caption says it does, the table serves as it's own source. But I question the merit of having an illegible table from 1907, and I think the caption mostly consists of trivia that doesn't belong in the article. I'm inclined to just delete the table.

Since April 19 is always replaced with April 18 for Epact 24, in order to keep Easter before April 26, so the ecclesiastical full moon is moved from Sunday, April 19 to Saturday, April 18, so April 26 is always replaced with April 19, and for the same reason with Epact 25 when the golden number is 12 or greater where April 18 is replaced with April 17 for the Ecclesiastical Full Moon, and the date of Easter (April 25) is substituted with April 18, for Epact 26 the ecclesiastical full moon (April 17) is never replaced with April 16, and the date of Easter (April 24) is never substituted with April 17 because the golden number would have to be higher than 22 and golden numbers cannot go above 19. So as a result every century has an April 18 Ecclesiastical Full Moon, with most of them having April 17, the centuries that don’t have an April 17 Ecclesiastical Full Moon is when Epact 25 is golden numbers 9, 10, and 11. 2603:6011:E00:4C41:0:0:0:1004 ( talk) 23:37, 27 December 2023 (UTC)
If we use the Astronomical Full Moon to determine when Easter is, the Astronomical Full Moon dates would range from March 21 to April 19, as March 20 is often the date of the Equinox, the additional day (April 19) would need to be included as the lunar month on average is 29 days, 12 hours, 44 minutes, and 3 seconds long that extra 12 hours, 44 minutes and 3 seconds would need to be added onto April 19, so Easter would occasionally fall as late as April 26 under this rule, and if April 19 is on a Monday through Saturday, the date of Easter wouldn't change if the full moon were to be one day earlier (April 18).
Although the true Astronomical Equinox is March 19, March 20, and March 21 depending on leap years and time zones (but the equinox is most often on March 20), so the Astronomical Easter Full Moon would range from March 21 to April 19. 2603:6011:E00:4C41:0:0:0:100D ( talk) 20:51, 30 January 2024 (UTC)
On the Hebrew calendar, passover starts on 15 Nisan, not 14 Nisan. Jonmlevinson ( talk) 13:14, 25 March 2024 (UTC)
In the Hebrew lunisolar calendar, Passover begins on the 14th day of Nisan.
It is conducted throughout the world on the eve of the 15th day of Nisan in the Hebrew calendar (i.e., at the start of the 15th; a Hebrew day begins at sunset).The "eve of the 15th day" is the 14th day, is it not? (That would imply that the Seder article is theologically wrong because formally it is conducted at the start of 15 Nisan, which to Gentiles is still the 14th for another six hours or so. To say "the eve of the 15th" seems rather inconsistent?) Either way, User:Jc3s5h's request #2 is critical. -- 𝕁𝕄𝔽 ( talk) 17:47, 25 March 2024 (UTC)

The very first paragraph summarises the "bottom line" of the lengthy article that follows as: Easter is celebrated on the first Sunday after [...] the first full moon on or after 21 March. There is no reference to time zone. However, the "date of the first full moon" depends on the time zone; the last Pascal Full Moon, e.g., was on 25 March 2024 UTC but on March 24, 2024 Pacific Standard Time. Alternatively, if one would define Easter not via the "fixed approximation" of 21 March but instead by the actual Vernal Equinox, then the phrase "first Sunday after" would need to be augmented by a time zone specification, as is done by the reform proposed in 1997, which references Jerusalem astronomical time. I don't know what the actual current definition is, but it should be included in the article. MsohniCam ( talk) 12:00, 1 April 2024 (UTC)
