I (m31) didn't wish my partner (f33) a happy International Womens Day and tell her I appreciate everything she does. Was I wrong to forget?

We have been together two years so this would be the second IWD that has passed during our time together. Last year she didn't say anything about it and has never mentioned that IWD is an important event for her and that she'd like me to celebrate it with her. We live in the UK and though it is mentioned on the news, IWD doesn't yet appear to be as widely celebrated as say Mothers Day or Valentines Day. So this year I heard about it fleetingly on the news but had a busy day at work so forgot about it. I text my partner in the morning wishing her a lovely day etc and that I couldn't wait to see her after work (we live separately). She texts back saying something similar, but around 2pm she texts 'are you aware its IWD?' And I said yes but only because I briefly heard it discussed on the news' to which she replied 'Okay.. Just letting your ignorant ass know that it'd be nice to appreciate the women in your life today'. I feel that was unnecessarily rude, as I do try to show her most weeks that I appreciate her and having spoken to my male friends most of them and their partners were not even aware that IWD had happened.
In hindsight now that I know IWD is important to her, of course I should have wished her a happy IWD. But I didn't know that it was important to her as she had never said anything. My partner was born in another country, one where women are regularly not respected or treated as equally as they are in the UK. Perhaps that has something to do with it, but surely she has to tell me at least once that it is important to her otherwise how would I know.

Was I in the wrong for not knowing IWD was important to her? For not celebrating a day that generally hasn't become a UK wide expectation like VD or MD? Was she too harsh with her response? Do you wish your partner a Happy IWD, or like me do you forget when it is unless you are reminded?
