As you may notice in my tranch of cards for 2026, I've got and labeled a card for each day of the year and they're separated with card dividers with each month labeled, so if I want to schedule something for December 27th, I pull out that card and write it down.

For more the more visual planners, you'll see the calendar card for the month at the front (labeled December 2025), and often I'll put big events there as well. I've got 12 cards like this for all of 2026.

For dates beyond 2026, I've got 12 monthly cards for each of the months on which I'll put advance dates. So for a future dentist appointment beyond 2026, I'll write in the day, the time, the dentist's name on the card for March 2027 and simply transfer it when that set of cards has been put together. This method also works if you don't want to do a whole year of cards in advance, but since I've been so consistent with them, it's much easier to spend an hour or so laying everything out a year in advance. I've also got a reminder card for changing the filters in my air conditioner and I'll file that right behind the card for the date it's due. If I didn't have cards going out so far, I'd just place it in date order at the back and file it once those dates had been created either a day or a month at a time. This flexibly allows you to plan as much or as little ahead as you like based on what you've got to hand.

There are examples in the Bullet Journal space for creating Future planning spreads which easily translate into index cards. (Any Bullet Journal spread you might do in a notebook can just as easily be done on an index card.)
