Or rather age:1d..1y
Posted under General
age:1d..1y returns all posts that are at least 1 day old, and are at most 1 year old.
Posts results are by default sorted by the most recent (highest ID) first, so you will get posts that are 1 day old on page 1.
Assuming you want to sort them in reverse, starting from a year old going back to one day old, you'll need to add a sort qualifier.
For example: age:1d..1y order:id which will return the oldest posts first.
