when does 500 document transaction quota renew?

[Bewitched_connoisseur7365]

I exhuasted my quota of 500 document transactions with the Adobe extract API. What is timeline for the 500 quota to renew on free tier? I created Acrobat Services account and started using API on approx April 18th and now it's May 18th. Do I have access to a new batch of 500 tranactions on May 19th or does it renew by  calendar month, i.e., June 1?

I believe it's calendar month.
