Good day Ubaidullah

If you are referring to the Calendar setup under Company Management > Calendar then there is unfortunately no way of doing an import to do a bulk update for the employees. You will manually need to link the employees to the applicable calendar setup.

If you are referring to the Public holiday setup on the company rule, you can do an import of the file and it will update the employees linked to the company rule.

Please refer to the following guide on how to load the Public Holiday calendar https://za-kb.sage.com/portal/app/portlets/results/viewsolution.jsp?solutionid=200511203214566&page=1&position=6&q=public%20holiday%202023

Kind regards
