What does this last date of joining mean ? Reporting in institution or beginning of course ??? When does course begin

Reporting institute n certificate verification

Usually course begins after round 2…not sure abt dis yr

Course begins on Feb 20,2022.

As soon as you do physical reporting and admission . Next day itself the course begins I guess. For example if reporting last date is 28 Jan then joining date will be next day itself.
