Get the addon for your Anki from here
Do you want to take a break from doing your Anki reviews without having them pile up on the weekends, holidays or a vacation? Or do you have specific days on the week when you're too busy to do the reviews? Then this add-on is the solution to your problem!
It works by re-scheduling the already scheduled cards anytime by moving them either before, or after the specified days. By default, the intervals never change by more than 10%, or by 7 days in any case.
This add-on plays well with mobile versions of Anki (AnkiMobile/AnkiDroid), assuming that the user also uses the desktop version, as the cards scheduled on mobile will be moved away from the specified days when the rescheduling is run (with Ctrl+Shift+r), or at every startup if run at startup is chosen at configuration options.
The add-on does not directly modify the scheduler, but instead reschedules already schedules cards, so it should play well with addons that patch the scheduler (for example, load balancer), but this is untested.
Before using the add-on reschedule:
After:
By default, the add-on will free up the weekends and nothing else. However, this behaviour can be changed to move the reviews away from specific dates and/or any day of the week.
Config can be edited in the Tools -> Add-on(Ctrl+Shift+A) -> Move Reviews from Weekends and Holidays. Make sure to restart Anki after editing the configuration.
Once you've set the dates and days of the week that you want to free up, you can use the shortcut Ctrl+Shift+r (by default) to reschedule the cards.
