66 Days until Opening Day?

I was trying to find the date for opening day. The MLB website has a lot of Opening Days apparently. First there's Boston v. Oakland in Tokyo on the 25th, which is the first official game. MLB is calling it 'Opening Day.'

Then there is the Civil Rights Game on the 29th, but somehow that is still a Spring Training game according to the Mets website. "Here you go, all you minorities. Sorry for being racist and marginalizing you. Here's a game for you. It doesn't count, but what the hell. The Japanese one counts though, because they have more money. Enjoy."

Then after playing in Japan, according to the A's website, Oakland then returns home to play a 3 game set against the Giants, which are all Spring Training games.

And Boston goes to LA for 3 games, including the one in the coluseum. They are also ST games.

How can you play Spring Training games after playing an offical game. Has they happened before? Nevermind. Teams play exhibition against minor league clubs and there's the HOF game which is an exhibition (unfortunately), but its still weird.

Then there is 'Opening Night' on the 30th, Braves v. Nats. This game does not appear to be nationally televised which is the only reason I can think of for this game to exist. Things could change though.

Then there is another "Opening Day" on the 31st. This is they day to celebrate because both the Tigers and the Cubs first play for real on this day.

EDIT: I just found this. Ok, the nats braves game is on ESPN and it will be the first game in the new Nat stadium. Makes sense.
