AITAH for saying our anniversary is NOT a holiday

My (22) parter and I (23) had our 4 year dating anniversary today. Earlier this winter we agreed that we would not be doing gifts for the holidays because money is tight right now. For family I sent small things to my siblings who are significantly younger than me but did not do anything for friends other than sending out holiday cards.

The problem came up yesterday when I was talking about how excited I am to give my partner their gift for our anniversary. When I said this my partner was mad and I was confused and asked why they were upset. They said we agreed to not give each other gifts this year for the holidays. I told them that I don’t consider our anniversary a holiday and that they also don’t have to give me anything, this is just something I wanted to do. They then went on about how it is unfair when people say they aren’t going to do gifts and then one does it anyways because it makes the other person look and feel bad. I once again said I don’t expect anything but our anniversary is also NOT a holiday. They said I lied about not giving gifts by making one. I felt terrible. In the end we agreed I would just give the gift next month for Valentine’s Day.

We have always given gifts for our anniversary usually something handmade. I had hand bound a book which I wrote out in calligraphy of poems/songs about love because we like to lay together while I read poetry to them out loud. It will be a good gift one day or another but I am sad and my partner still says I’m at fault for “lying”.

Do you guys think? Is it a holiday?
