I set a daily review limit for some of my Anki decks at 30 cards per day. However, as I go through these daily reviews, I sometimes manually set a due date for certain cards. But I noticed that it then doesn’t count toward my review limit for the day. So I will actually end up reviewing 30+ cards per day instead of 30. How can I fix this so that setting the due date for a review card will make it count toward my daily review limit?
That’s true. Set Due Date isn’t recorded as card-study event. There’s nothing you can do to change that.
Can you explain why you are using Set Due Date instead of grading the card normally in your study session? That should be a rare situation, so if you’re doing it often, there might be a better way to accomplish your goal.
I stopped studying my decks a while ago, so I built up a lot of review cards. So when kind of get the card right but not completely, my only options for the next review date is 7+ months out. I don’t want the next review date to be that long but I don’t want to redo the card and then have it due in the next 2 days. If that makes sense.
I understand what you’re saying, but you might be overlooking the reason why that next interval would be so long. If you’ve remembered that information through this break in your studying, you don’t need to study it again sooner than that. Anki takes that into account. See Due times after a break - Anki FAQs (the FSRS algorithm follows similar logic, but uses different formulas).
This also sounds like you’re using an add-on to hide the Hard button (and maybe the Easy button too?). Using all 4 buttons is also an option. Studying - Anki Manual
But hopefully you’ve also enabled FSRS, which deals with post-lapse intervals better than the default SM-2 algorithm. So if you need to grade that card Again, it will graduate from Relearn with more accurate scheduling.
By using Set Due Date, you’re essentially postponing this review, which just postpones the problem too. The next time this card comes up, Anki will still see that it’s been months since you’ve studied it, and it will still try to set a long next interval if you get it right.
If you don’t want to change anything else about your grading habits, you should at least grade the card first – honestly, accurately, and without considering the next interval – so that it will set a starting line for the card’s scheduling in the future. Then you can find the card in the Browse window and use Set Due Date to overrule the algorithm’s decision about scheduling if you need to.
