SSRS reports

So my company is looking to standardize date format over all SSRS reports, is there a “massive” way to do so rather than 1-by-1?
We are talking about 1,000+ forms… Any idea?
Thanks in advance

The date format is control by the User Account Maintenance Language and Format Culture

UK: dd/mm/yyyy
US: mm/dd/yyyy

Etc etc etc…

Expanding on Aaron’s post -

When Reports and background Tasks are run, they are run “As” the user that submitted the Report / Task. As a result, the Language and Culture specified on the User record of the person submitting the job are applied during the processing.
