Wrong for wedding day after sisters birthday?

Absolutely not wrong! She's being ridiculous and dramatic. I know birthdays are more important to some people than to others - especially milestone birthdays - but as a grown adult she should realize the world doesn't stop because it's her birthday (and even the day after!!). So sorry you have to deal with that.

Nope. Don't think you're in the wrong at all. It's not a milestone birthday, so I don't see why it's really that important. She hasn't made plans yet, bought tickets or paid for anything, so she literally has little to no reason to get upset lol. Just like a couple gets one DAY for their wedding, the same applies to birthDAYs. It's unfortunate that she's acting this way, but I wouldn't pay any more mind to her. If she wants to act this way, then so be it.

I'm guessing there may be another element to this...I'm not positive from the original post's wording, but perhaps she heard about you guys setting a new wedding plan through the grapevine, without you guys giving her a heads up or consulting her as the Maid of Honor? If that was the case (and i'm not sure it was), maybe it's not entirely about the day/birthday weekend/scheduling aspect....perhaps it's a little bit of that and a little bit of "oh my gosh, my sister set a wedding plan, and i found out through someone else besides her...now people might forget about my birthday entirely, and perhaps she even forgot about me already in terms of running the idea by me"...just throwing out an alternative theory in case it's helpful! Maybe a small olive branch-type gesture to recognize her birthday somehow? I don't really know what that would look like, and I also could be wayyyy off...but I wish you luck in navigating this situation and in wedding planning!!

Dude my wedding was ON my best friend's birthday and she was MOH. she didn't care. she was like it works better for your schedule, so whatever, it's fine aha. so what you're asking for isn't even ridiculous

I don't think you're wrong at all. While it might be her birthday weekend, she can always plan something for the weekend before or weekend after. I mean, everyone kind of has to sacrifice their birthday at least once in their lifetime, and why would she be mad about doing that for her sister to get married, ESPECIALLY after you had to postpone? Can you explain to her that while you understand she wants to celebrate her birthday, wedding planning lately has been EXTREMELY tough and dates are becoming very limited, plus the date has meaning to you and your FH and that is why you chose the date? I mean, it doesn't sound like she's going to listen, but maybe it's worth a shot. If she continues to act that way, then I guess you're better off moving on without her being your MOH.

She's 30 years old?!

You're not even a little wrong. Especially if she hasn't planned the trip - she sounds like she's just hunting for drama.

It sounds like the selfish and inconsiderate one is your sister, not you! You and your fiancé are allowed to get married whatever date you want. Do not feel bad and do not change your plans. I hope she realizes what a big mistake she is making by acting this way and comes to her senses.

Ah ok! No need to apologize at all!! I was just wondering if she mayyy have heard through someone else because I thought the reaction may have been a bit strong for you telling her directly. Ok so that is an even tougher situation than I had thought. I really hope she comes around. If you communicated with her directly, I actually agree with the other Allie (lol!!!) that perhaps she doesn't have a full appreciation for trying to plan a wedding during a pandemic - trying to keep your loved ones safe while also getting legally married while also celebrating and gathering with your nearest and dearest. It's not easy!! Maybe she's getting caught up in the birthday excitement and not realizing that getting married is a big life event!

You get one day and she gets one day. As long as they are on separate days, she's overreacting.
