All Filofax diaries come preprinted with national and international holidays, but when it comes to personal holidays, like birthdays, you can do it your way.
Do you write them in your new diary at the beginning of every year? Do you keep them on separate sheets that you can carry over from year to year? Or do you print them into your own self-printed inserts?
Whichever way you choose, how do you remind yourself in advance of the date so you'll be ready with card, gift, etc.?
As always, all organizer-related topics are welcome!
