Next up is the Arabian Horse World Cup. I'm taking a pass on that, not out of disrespect for Arabians but bc I'm not even remotely qualified to wager on this one! #HorseRacing #ArcDay

I've never heard about an ‘arcday’, but arcminutes and arcseconds are definitely a thing! (and occasionally arcthirds etc)

lol! I was just just thinking about this -- randomly started leafing through "Astronomical Algorithms" by Jean Meeus

we don't use "arc" enough when speaking of time. the degree world gets "arcminute" (1/60 of a degree), which is 1/21600 of a circle.

like "arcday" could be 4 minutes (for real!).

Puerto Rico, the winner, looks like Black Beauty. Almost suggested literary ppl have some money on, just for that, but the odds were a bit shite. #Lagardere #ArcDay
