We do not make this decision lightly, and we apologise for any inconvenience. The workaround is to clone and/or modify the HRJ Holiday Calendar widget to include the following changes: In the Server script //After this if statement... if (data.calendars.length > 0) getCalendarData(data.calendars[0]); //Add this line data.userDateFormat = gs.getDateFormat(); In the Link //Change this line return moment(date).format('dddd, MMM Do YYYY'); // To this return moment(date, scope.data.userDateFormat).format('dddd, MMM Do YYYY'); Related Problem: PRB1354497
