This is how we can change the interval for an individual card deck in anki.
Simple settings
Learning steps=
One or more delays, separated by spaces. The first delay will be used when you press the Again button on a new card, and is 1 minute by default. The Good button will advance to the next step, which is 10 minutes by default. Once all steps have been passed, the card will become a review card, and will appear on a different day. Delays are typically minutes (eg 1m) or days (eg 2d), but hours (eg 1h) and seconds (eg 30s) are also supported.
Graduating interval=
The number of days to wait before showing a card again, after the Good button is pressed on the final learning step.
Easy interval=
The number of days to wait before showing a card again, after the Good button is pressed on the final learning step.
Advanced settings
Maximum interval=
The maximum number of days a review card will wait. When reviews have reached the limit, Hard, Good and Easy will all give the same delay. The shorter you set this, the greater your workload will be.
Starting ease=
The ease multiplier new cards start with. By default, the Good button on a newly-learned card will delay the next review by 2.5x the previous delay.
Easy bonus=
An extra multiplier that is applied to a review card’s interval when you rate it Easy.
Interval modifier=
This multiplier is applied to all reviews, and minor adjustments can be used to make Anki more conservative or aggressive in its scheduling. Please see the manual before changing this option.
Hard interval=
The multiplier applied to a review interval when answering Hard.
New interval=
The multiplier applied to a review interval when answering Again.
