Sport's Day or Sports Day?

[maresedotes]

I asked a medal supplier whether a "Sport's Day" medal could be changed to "Sports Day" and was told both are correct, ie it could be a day of sport (sport's day) or lots of sports (sports day). Surely not - am very happy to be corrected (well a little)!

I would go for Sports Day of those two options, but I write Sports' Day (as it's a Day of Sports, plural).

Sports Day. The day doesn't belong to 'sport'. Unless there is a Mr Sport and you are celebrating his birthday...

Sports Day.

Yup. Sports is descriptive or indicative, not possessive.
