When to send save the dates- June 2017 wedding

Hello everyone! First time poster, long time lurker I apologize in advance, since there are many similar threads and Google already gave me an answer on this (I just want some opinions!!!) My wedding is June 10th, 2017 and I ordered my save the date cards to take advantage of a great coupon from Minted... my question is- when the heck do I send them out!? About half of our guests will be OOT guests (some driving, some flying), and I think almost everyone already knows the date. I was thinking our invitations will go out mid-March (RSVP by May 10th) and that our STDs should go out in the beginning of November.. Is this crazy? I don't want them to get lost in the holiday card shuffle of December, and everyone is so excited so I do want to get them out kind of soon. Thanks in advance for any advice, especially from fellow June 2017 brides!
