How can we add a number of holidays in the CA SDM Calendar?
Holidays are entered as part of "workshifts" in CA Service Desk. We have a document that explains a bit more about how this works - you can find the document here: https://www.ca.com/us/services-support/ca-support/ca-support-online/knowledge-base-articles.tec599190.html
Hope this helps,

SDM is a widely used product worldwide so it could be messy to add holidays to the calendar. It could be a better idea
to have each site to custom there own calendar, by modify/create new work shifts.
if you business idea/goal is that to not have change been process during holidays or at less been warned that change will be performed during a "holliday period" (note sure that this is holliday then )..
You may then want to simply use the blackout window for it.
my 2 cents
