message: The introduction should be shorter. Right now it redundantly states things that will be repeated later on. It is also difficult to understand.--Gheuf 19:24, 25 January 2007 (UTC)

message: I'm wondering about some points.  Perhaps the answers could be included in the article.
- where the name dominical comes from?
- is the Dominical letter system still in use?
One specific question.  The 3rd paragraph of the article says "In the original 1582 Catholic version, it did, but in the 1752 Anglican version it did not. "  Versions of what?  It is not clear to me if 'version' refers to a) versions of the calendar, or b) versions of the Dominical letter system.
Thanks.   Wanderer57 14:47, 30 September 2007 (UTC)
replies: text: Dominical comes from the Latin word dominica, meaning Sunday. In a year with a dominical letter A, then days marked with an A in the Calendar are Sundays. In B years, b days are Sundays, etc. Rwflammang (talk) 19:30, 20 January 2010 (UTC)

message: What is the dominical letter of 1712 in the Swedish calendar?? Georgia guy (talk) 01:31, 26 November 2007 (UTC)
replies: text: Very interesting question! The year 1712 in the Swedish calendar had two leap days, February 29 & 30. The extra leap day restored that year to the Julian calendar after the year 1700 when it skipped a leap day, and 1704 and 1708 when Julian leap days were included. Using Calendrica, January 1 was a Tuesday in the Julian calendar. A lost leap day in 1700 meant that the Swedish January 1, 1712 was a Monday. Regarding it as A, the next Sunday is G. The two leap days decreased the Dominical letter to E. So the Dominical letter of 1712 in Sweden was GE, G for the Sundays between January 1 and February 28, and E for the Sundays between March 1 to December 31. This is confirmed by Easter Sunday/Jewish Passover Calculator by Robert van Gent, which yields FE for a normal Julian year of 1712. — Joe Kress (talk) 05:50, 26 November 2007 (UTC)

thread_title:  Sequence 

message: In  The odd plus 11 method
: Count forward T letters from the century's dominical letter (A, C, E or G see above) to get the year's dominical letter.
The only plausible candidate for (the description) "above" that is in §  Calculation: 
: for one century within two multiples of 400, go forward two letters from BA for 2000, hence C, E, G.
That is not at all clear, at least to readers not already familiar with the dominical calculations. It needs rewriting, to make the procedure comprehensible and accessible to the ordinary reader. --Thnidu (talk) 20:45, 9 July 2017 (UTC)
replies: text: I came here because I did not understand the meaning of "the century's dominical letter". This needs to be clarified indeed. Where does the "A" come from? A well-chosen example or two might do wonders to make this comprehensible.  --Lambiam 07:40, 23 August 2020 (UTC)
thread_title:  Century letter 

message: "Dominical letters are derived from the Roman practice of marking the repeating sequence of eight letters A–H (commencing with A on 1 January) on stone calendars to indicate each day's position in the eight-day market week (nundinae)."
"Thus, 2017 is A, indicating that all A days are Sunday, and by inference, 1 January 2017 is a Sunday."
Well... no.  January 1, 2017 is a Sunday.  If the letters A-H are used, the next Sunday, January 8, 2017 will be H, and the next "A" day will be a Monday, January 8, 2017.  The next A day will be a Tuesday, the next will be Wednesday, then Thursday, and so on -- there will be seven full weeks between weeks in which Sundays are A days.
Some part of the given definition is wrong.  — Preceding unsigned comment added by 74.95.43.249 (talk) 00:05, 11 April 2018 (UTC)
replies: text: Well... no. You just skipped a section in there that already explained the difference and the given definition is fine and was fine when you made this note. — LlywelynII 21:54, 11 May 2024 (UTC)

message: Start of this section doesn't make sense. Seems like Friday the 13th is just shoved into there as trivia. Slywriter (talk) 02:26, 19 August 2022 (UTC)
replies: text: Yup. Came to the talk page to look for exactly this. Absolutely no importance to the topic and should be removed, unless there is a notable group of people using the dominical letters to actually calculate for F13 instead of Easter. You could do the exact same thing with July 4th, May the Fourth Be With You, or Pi Day, but they're just as off topic. — LlywelynII 21:52, 11 May 2024 (UTC)
