One "simple" way to know when a user started editing is download the
full history file as XML, not PBF, and look for the first changeset made
by a mapper.
The account_created on the user details will tell you when the account
was created, and normally they start editing shortly afterwards, but
there are a tiny amount who only start editing years after creating an
account. e.g. https://www.openstreetmap.org/user/SimonPoole/diary/34856

Hi Janet,
The OSM API can give details about when a user created their account,
and how many changesets they have contributed.
https://wiki.openstreetmap.org/wiki/API_v0.6#Details_of_a_user
While the API will tell you how many changesets a user is up to right
now, it’s not easy to know how new the user was at the time they made an
edit. For this reason, the next version of iD will also include the
user's `changesets_count` as a tag on each changeset, to make this
analysis a bit easier.
Thanks,
Bryan

Does anyone know how to analyse when mappers in a particular

Any advice appreciated, thanks.
