Work Time Tracking Calendar for Jira v 5.3.x: Hide Weekends

You can hide or show the weekends in a particular calendar by unticking or ticking the Weekends checkbox, in the calendar period drop-down.

Please be cautious with this setting. When weekends are hidden, the events that fall on weekends will not be shown on your calendar. Although, their times will be included into Total, Sources and Users sub-totals, on the left panel.
