Talk:2431: Leap Year 2021

It's amazing how quickly some of us got to edit this. I hope I didn't cause too much edit-conflict confusion just by my changing the date value. Honestly just checked, before turning in, to find two (so far) other edits follow so quickly after... 141.101.98.152 02:03, 2 March 2021 (UTC)

Sorry,I did not see anything when I started

I wouldn't expect you to (the first Categories adder, yes?), until you perhaps tried to save. But that's what being shown edit-conflicts is important for. 141.101.98.244 03:02, 2 March 2021 (UTC)

If someone actually did this, how many years would it take for the calendar to line back up again where it started? 365? Captain Video (talk) 02:20, 2 March 2021 (UTC)

365 years plus (around) 33% more because every fourth year (except every hundredth, except except every 400th) is already expected to have a 29th, so you'd not be able to shift the year that year and have to do those days after the first 365 mostly-shifted consecutive years - with the necessary overflow days still being only to be done for 3/4(ish) of the next 91ish years, leaving maybe 23 more years to be shifted. But 24 years would only allow 18 shifts, so 6 more years than that probably would use 5 years. And one year may be absorbed already, or left over. So 365+91+23+6. Ish. Because it'd depend exactly which year you start as to which non-expandable years occur within the strict (0.75)+(0.25*0.75)+(0.25*0.25*0.75)+... series. But that's the likely area of the answer, off the top of my head. Around 485 years, give or take. Unless I've made a big error! 141.101.98.244 03:02, 2 March 2021 (UTC)

Can someone make a Category:Calendar that is a subcategory of Category:Time? I feel like there are several comics that could fit, e.g. 994: Advent Calendar, 1140: Calendar of Meaningful Dates, 1930: Calendar Facts, 1073: Weekend, 1061: EST, etc. 162.158.255.210 02:39, 2 March 2021 (UTC)
