The idea is to use a single not for the same day throughout all the years. So there will be one note called '2 May' and it will contain this years information. You can retro-actively enter (links to?) information from previous years on the same day.
Next year you will add the information for 2 May 2026 into the already existing note '2 May'
If you create a like in your ✱Home note to shortcuts://run-shortcut?name=Open%20Today%E2%80%99s%20Note that link will always open the correct note for that day.
