Countdown in header text

• On January 10th 2021 a countdown appeared in the top right corner of the header text of xkcd.
• This happened while the comic 2565: Latency was up.
  • First the xkcd Header text was changed back to the standard text for the first time in almost three years:
  • xkcd updates every Monday, Wednesday, and Friday.
• But already while this Friday-comic was still up on Monday a countdown was added.
  • This was thus up when the Monday comic 2566: Decorative Constants was released, drawing more to the xkcd page.
• The first archived version from 2022-01-10 read 20d 20h 27m.
  • It looks like it started on 01-10 17:00 UTC.
• This countdown will reach zero on Monday 2022-01-31 at 14:59 (2:59 PM) UTC, or 9:59 AM in Boston, Randall's home town.
  • If seconds will be added towards the end, it seems likely that it may end at 15:00 UTC exactly.
• At 2022-01-11 a diagonal black bar appeared in the lower left-hand corner of the countdown box.
  • This development called for the creation of this dedicated Countdown in header text page.
