Consistency in names for decades.

Various templates for grouping establishment and disestablishment for decades such as Template:Sports clubs and teams (dis)established in the YYY0s category header use the value of the category it was in to calculate a link to the decade. So for example, when placed in Category:Sports_clubs_and_teams_established_in_the_1940s , part of the output is

This category is for sports clubs and sports teams established in the 1940s.

However, this becomes an issue when placed in Category:Sports_clubs_and_teams_established_in_the_1800s , as 1800s is a dab page between that decade and the 19th century. 1900s on the other hand is the page for the decade. (other pages earlier in time like 1700s are also dab pages.) So I'd like to either see the XY00s pages consistently refer to decades *or* have redirects for all decades so they can be accessed like the 1800s, so for example 1920s (decade) would be a redirect to 1920s so that the templates could have the internal code generate a piped like to there (so instead of a link to 1920s, it would be to [[1920s (decade)|1920s]].

After deeper dive, found template:Decade link. I think I can use that.Naraht (talk) 03:23, 13 October 2025 (UTC)

Discussion about WikiProject banner templates

For WikiProjects that participate in rating articles, the banners for talk pages usually say something like:

• "This article has been rated as Low-importance on the importance scale."

There is a proposal to change the default wording on the banners to say "priority" instead of "importance". This could affect the template for your group. Please join the discussion at Wikipedia talk:WikiProject Council#Proposal to update wording on WikiProject banners.

Weekday templates that claim to follow ISO weekday number, but don't

I noticed some templates that claim to follow ISO week date (e.g. consistent with date computing with Julian day, ISO week or ISO year computations), but actually follow a different convention of the ISO week day number (0=Monday..6=Sunday): (lists probably incomplete)

• {{CURRENTWEEKDAY}}: {{CURRENTWEEKDAY}} → 7
  • Compare with {{#time}}: {{#time:N "for" l}} → 7 for Sunday
• {{WEEKDAYNUMBER}}: {{WEEKDAYNUMBER|Thursday}} → 4

With some templates that follow such convention, without claiming that they follow the ISO week format:

• {{Weekday}}: {{Weekday|2025|12|25}} → 4
  • Compare with {{#time}}: {{#time:N "for" l|2025-12-25}} → 4 for Thursday
• {{WEEKDAYNAME}}: {{WEEKDAYNAME|3}} → Wednesday
• {{WEEKDAYABBREV}}: {{WEEKDAYABBREV|3}} → Wed

These templates have existed for a long time with this behaviour. They are not widely used in articles, but are used in e.g. WP:Main Page/Errors and Template:Quicktemplates.

Apparently such convention is to be consistent with {{JULIANDAY}} mod 7, which is how {{Weekday}} is implemented:

• {{JULIANDAY|2025|12|25}} → 2461035
• {{WEEKDAYNAME|{{JULIANDAY|2025|12|25}}}} → Wednesday

To clarify such non-standard format, I propose to:

1. Remove mentions of the ISO format from their docs;
2. Migrate uses of these templates, possibly to calculations using {{CURRENTDOW}} (0 (for Sunday) through 6 (for Saturday), not ISO);
3. Either rename these templates, for example with "JULIANWEEKDAY" to contrast with "ISOWEEKDAY", or introduce an explicit |julianday= parameter to these templates; and
4. Have these templates return or accept ISO weekday numbering by default.

Then there are:

• {{Weekday in month}}: Mentions The weekday numbering follows ISO practice (Sunday → 0, Monday → 1, ... Saturday → 6).
  • I propose to just remove mentions of ISO practice, discourage weekday argument in number, and prefer in English word.
• {{Weekday in month elapsed}}: Passes arguments to {{Weekday in month}}. Calls {{CURRENTISOYEAR}} (instead of {{CURRENTYEAR}}) for no apparent reason, which is error prone near the start or end of year. Doesn't actually check other arguments if year is provided.
  • {{Weekday in month elapsed|2025|12|Wednesday|last}} → 1
  • {{Weekday in month elapsed|2026|1|Thursday|first}} → 0
  • {{Weekday in month elapsed||12|Monday|last}} → 0
• {{Weekday in month recurring}}: Calls {{Weekday in month}}, {{Weekday in month elapsed}}, and {{CURRENTISOYEAR}}.

— Peterwhy (talk) 05:02, 28 December 2025 (UTC)

Changed the first 5 templates listed above, to follow the ISO format:

• {{CURRENTWEEKDAY}}: {{CURRENTWEEKDAY}} → 7
  • Compare with {{#time}}: {{#time:N "for" l}} → 7 for Sunday
• {{WEEKDAYNUMBER}}: {{WEEKDAYNUMBER|Sunday}} → 7
• {{WEEKDAYNAME}}: {{WEEKDAYNAME|7}} → Sunday
• {{WEEKDAYABBREV}}: {{WEEKDAYABBREV|7}} → Sun
• {{Weekday}}: {{Weekday|2026|01|18}} → 7
  • Compare with {{#time}}: {{#time:N "for" l|2026-01-18}} → 7 for Sunday

Created {{JULIANDAY.DAYNAME}} to extract the day name from JD, similar to templates like {{JULIANDAY.DAY}}, {{JULIANDAY.MONTH}}, etc.:

• {{JULIANDAY|2026|01|18}} → 2461059
• {{JULIANDAY.DAYNAME|{{JULIANDAY|2026|01|18}}}} → Sunday

Converted callers of {{Weekday in month}}, {{Weekday in month elapsed}} and {{Weekday in month recurring}} that set numeric day of week. — Peterwhy (talk) 05:59, 13 January 2026 (UTC)

Wow! Did I really make some date templates 20 years ago? Amazing that they are still in use today. --Uncle Ed (talk) 04:39, 24 February 2026 (UTC)

• {{Weekday}}
• {{Weekday in month}}

Geological epochs

Hi! I've been editing pages from the South American Land Mammal Ages, when I noticed that the main SALMA page is part of WikiProject Time. As none of the associated pages were attached to this project, I started to add this project onto them. However, after reviewing much more popular geological epochs (such as Maastrichtian, Pleistocene, Holocene), I saw that they aren't attached to this project. Can someone clarify whether geological / faunal ages should be attached to this project? SuperTah (talk) 04:29, 28 December 2025 (UTC)

From our scope statement, The principal articles with which this project deals are included in the Category:Time or one of its subcategories. The master categories for these epoch articles appears to be Category:Geology timelines and I don't see a connection between this and Category:Time. Maybe there should be. ~Kvng (talk) 15:28, 15 January 2026 (UTC)

Proposed "Day of the month" articles

I'm thinking about writing a series of articles on ordinal days of the month at, e.g., First day of the month, Second day of the month, Third day of the month, all the way up to Thirty-first day of the month, to expand on commonalities of days of the month by ordinal position. I think this is a missing ground between existing articles on days of the week and days of the year. BD2412 T 15:56, 13 February 2026 (UTC)

After further examination and consideration I have decided that a series of set index articles will suffice for this purpose. BD2412 T 03:07, 24 February 2026 (UTC)
