I moved from Windows to Mac. I have never missed a day in my Anki history. After downloading and logging in on Mac, and then syncing from the cloud. I’m now showed several days missing where it says I did no reviews for some reason. The pattern seems to be random. A few days here and there, never more than one at a time.
Is there any way to fix this?
First, try running a Check Database – it is a cure for multitude of things.
Then – I notice that a lot of those gaps have a double-dose of reviews right next to them. That usually indicates that your review history isn’t lined up correctly with what a “day” is. Are you computers set to the same time zone and locale settings? Do you have the same next-day-starts time in Preferences > Review?
Check database did nothing. However, I did change my timezone 6 hours ahead because I moved overseas. I guess that is the problem. Is there no way to fix that without using the previous (now wrong) timezone?
Aha! Yep, that’s it.
Changing time zones shifts how the “days” line up with your review history – so it looks like there are now some 24-hour periods with any reviews. I assume this is a permanent/semi-permanent move?
If it’s important to you to close those gaps, you’ve got a couple of options –
Tweak the next-day-starts time. – It is set to 4am in your time zone by default, because it should be deep in your sleeping hours where you won’t be studying anywhere near it. But depending on your sleeping/studying habits, a couple hours in either direction might still be an appropriate next-day-start. If you look at some of those double-dose days, is there a batch of reviews that is close to the 4am line? How close?
Paper over those gaps with a little time-machine magic. You might want to add a garbage note/card just for this purpose, so you don’t muck up your review history for anything that matters.
