Two for Twosday

Is this pair of dual-humped Bactrian camels heralding hump day? Nope, it's not quite Wednesday yet—but you can double down on your celebratory mood this February 22, because Tuesday 2/22/22 only occurs a couple times a millennium. (Every 400 years, to be exact.) So on this deuce of a day, beware of two-timers claiming they'll pay you back next Twosday—you'll be short your two bits until February 22, 2422.
