This idea has been merged into another idea. To comment or vote on this idea, please visit APP-I-1897 Display Holidays in the GANTT chart.
We would like to show public holidays and office closures on the Releases Gantt chart as a faint vertical bar similar to that shown in MS Project (screenshot). Ideally this would be implemented as a call to a remote REST API which returns iCal format data. An alternative may be to manually upload a file containing this data (iCal).
