What does mean the time closest to the branch name?

In local branch there is a number with a letter and this changes when i checkout between diferent branches but no idea what represents.

Thanks you.

The number and letter are a short way of expressing how long its been since that branch was updated:

1w = "one week"
4d = "four days"
2y = "two years"

etc.
