New profile.

Your question is unclear.
Is this company one you work for?
Are you talking about a website, perhaps this one, a2k?
Or another one, perhaps facebook?

The same day that what happened? That you got a job, or that you signed up to a website?

Yes, you can back date events to before you joined Facebook. Not sure about posts and photos. Why not try and see what happens?

I am 85% sure you won't summon a demon if you try to backdate photos.

My wife started and work in a small hairdresser salon.
We did make our business fb profil yesterday and she started her salon in mid of January.

We want to put in Picture and coment those at different date from start date and up to now. We hope that we can turn back the clock and put in this information at the date that it truly happend. :-)

Best regard Frode.

I doubt that you can backdate comments or the upload date for images. But you can definitely put in older events (e. g. people put in their birthdates and their wedding dates all the time).
