Do Not Disturb
You can set a DND timer to suppress all alarms and sounds temporarily.
In a meeting? Sharing your screen with someone else? Projecting slides in a staff meeting? You probably don't want personal alarms to popup in the middle of any of this, or alarm sounds to go off during an intense discussion. With BusyCal's built-in Do Not Disturb function, you can temporarily suppress all alarms and sounds, and have DND turn off automatically after the specified duration.
The DND toggle button can be accessed from the toolbar, along with a dropdown to choose the time you wish for alarms to remain suppressed.
Click on the down-arrow to select a duration, and then click on the moon icon to toggle between ON and OFF DND modes.
