Because the date/time it displays for the vast majority of Global players (well, at least most of those who use this Wiki on a regular basis, anyway) is the 23rd to 30th. Additionally, when announcements are put out in-game (upcoming Guild Wars or Raids, for instance), the times are always stated in Pacific time, which is a US timezone, so everything on this site is based off US timezones (and therefore US dates).
