AITAH for not changing the time of my grandmothers 87th birthday party for a Canadian FIFA soccer game?

As the title reads, I am hosting my grandmothers 87th birthday party at my house tomorrow (Saturday). Originally the party was going to be at my grandmothers place, but she’s going through health issues and isn’t up for hosting. I am the only one on my family who has a house suitable for hosting us all (9 people total).

My grandmothers birthday was Thursday, and most of us work during the week, so Saturday was the day we set a few weeks ago to celebrate her.

My husband just asked if we can change the time of the party tomorrow so he can watch the Canadian FIFA soccer game tomorrow (he has never mentioned the game before when we talked about the party). He is a huge sports guy in general, specifically football and hockey, but he honestly doesn’t really watch soccer.

We are having the party from 1:30/2ish to 5, as we are not having dinner and are just having some afternoon snacks. My grandmas health issues are causing her to get uncomfortable and in pain quick, so a relaxing afternoon of nibbles and drinks with the opportunity for her to leave anytime she needs seemed like the best option.

My husband wants us to push the party by 30 min to an hour so he can watch the whole game and I said no because I don’t want it to linger into dinner time. And I don’t think we should be changing the time of a party with 9 people coming so he can watch the game. He said I’m not considering his side and that I’m an AH. Am I?
