Users sometimes ask when the stock return, price or volume data in Eventus will be updated. Eventus itself is an empirical analysis package and doesn't include data. The data set that Eventus uses by default is the CRSP U.S. Stock Database to which your institution subscribes.
When the CRSP database is updated and whether Eventus "sees" the new data depend on 1) when CRSP delivers the new data -- to WRDS, or to your institution in the case of Eventus for Windows -- 2) when someone installs the data and 3) whether the pointers Eventus looks for are updated to point to the new edition of CRSP. In the case of WRDS, WRDS staff are responsible for maintaining both the CRSP database and the link between Eventus and CRSP. In the case of locally installed Eventus, information on how Eventus finds CRSP is available in Appendix C of the Eventus User's Guide.
If you need information on the update schedule, please check with CRSP, WRDS or whomever supports locally installed CRSP and Eventus at your institution, as applicable.
