Talk:Leap year

message: ;Algorithm
The following pseudocode determines whether a year is a leap year or a common year in the Gregorian calendar (and in the proleptic Gregorian calendar before 1582).  The year variable being tested is the integer representing the number of the year in the Gregorian calendar, and the tests are arranged to dispatch the most common cases first.  Care should be taken in translating mathematical integer divisibility into specific programming languages.
if (year is not exactly divisible by 4) then (it is a common year)
else
if (year is not exactly divisible by 100) then (it is a leap year)
else 
if (year is not exactly divisible by 400) then (it is a common year)
else (it is a leap year)
;Excel
This algorithm translates into Excel like this, whereas year stands for the cell which refers to the input cell:
=IF(NOT((year/4=TRUNC(year/4)));"common year";IF(NOT((year/100=TRUNC(year/100)));"leap year";IF(NOT((year/400=TRUNC(year/400)));"common year";"leap year")))
or reversed, more simplified:
=IF((year/400=TRUNC(year/400));"leap year";IF((year/100=TRUNC(year/100));"common  year";IF((year/4=TRUNC(year/4));"leap year";"common  year"))

: Fine, but an Excel formula is not the sort of thing WP would ordinarily supply. The shape of the algorithm in pseudo-code is appropriate, but translations into specific languages generally not. -- Elphion (talk) 17:51, 26 August 2015 (UTC)
thread_title:  section Algorithm: adding Excel example 

message: Can anyone provide a convincing case for retention of the section . It looks to me like one editor's pet project. At , we already have the concise statement 
 with a sensibly-sized graphic beside it. What value does this "Algorithm" section add over and above what has been said already? How is it not a WP:NOTMANUAL violation? Furthermore its suggestion that it has any validity before 1582, let alone in the years BC/BCE, is surely just wrong? 𝕁𝕄𝔽 (talk) 11:17, 21 December 2022 (UTC)
replies: text: Pending discussion, I have moved it to the end of the article where at least it (and its giant graphic) are not so disruptive. --𝕁𝕄𝔽 (talk) 13:21, 21 December 2022 (UTC)

text: Could the section be moved to https://en.wikipedia.org/wiki/Leap_year_problem, where there is now a dead link to the algorithm? 2A02:8010:6008:0:A829:F7:2B5D:F60 (talk) 10:27, 19 September 2023 (UTC)
thread_title:  Section "Algorithm" - why? 

message: In the archives there is a thread about this, Talk:Leap year/Archive 3#What citation format?. I believe what was said there still holds, use  rather than . However, when formats where the elements of the citation are separated by commas, as with the Chicago Manual of Style footnote style, are used for the endnotes, bibliographies commonly separate the elements with periods. Since the Sources section resembles a bibliography, I have left the "cite xxx" templates there as they were. Jc3s5h (talk) 16:37, 7 August 2023 (UTC)

message: i have noticed on my farm in trinidad many of my plants and fruit trees bear twice during a leap year i am from a tropical country in the carribbean can anyone contest to this? Gramchees (talk) 12:13, 20 August 2023 (UTC)
replies: text: This is strictly anecdotal, and not very credible as a general phenomenon. A reliable source would help. -- Elphion (talk) 16:25, 20 August 2023 (UTC)
thread_title:  certain trees and plants bear twice during a leap year  

message: I think that the information is repeated in this article. We have first a section called "Julian calendar" and, then, another one called "Julian reform" with the same information but more elaborated. It would be interesting to merge if you agree that it is a repetition. Theklan (talk) 10:22, 31 January 2024 (UTC)
replies: text: I'll look closer. But in the mean time, I restored Theklan's removal of the section on the Revised Julian calendar because that is different from the Julian calendar. Jc3s5h (talk) 16:15, 31 January 2024 (UTC)
