Based on the comments, a lot of people have trouble remembering this stuff. Don’t get me wrong, I do too. Most calendar apps (Google, Outlook, idk others) have reminders you can set however much time in advance you need, for whatever sort of event or reminder you need. For a lot of birthdays I’ll have a month before reminder so I can order something online or remember to pick something up, two weeks reminder so I can either check on shipping or in case I forgot to get whatever I thought of, a week reminder because I might have forgotten twice before or whatever needs to ship, then day of or day before so I can tell the person so it doesn’t seem like I forgot already 3 times even with reminders.
