Dear all,
* We run Jira Service Management 4.20.1
* I recently updated the SLA calendar on our IT Helpdesk project, using a government annually piblished ical with public holidays for 2022
* I then manually add the days on top of the public holidays in the ical, that we are closed for the year
* We are usually given a 1/2 day on the last business day before Christmas
* I don't see in Jira a means to add anything other than full day holidays to the calendar

* Could someone direct me how to add a 1/2 day to the calendar please?
Thanks for any help.
Regards,
Steve
