Apparatuses, methods, and program products are disclosed for calendar control. One apparatus includes a processor, and a memory that stores code executable by the processor. The code is executable by the processor to detect a triggering calendar entry of multiple calendar entries in a first digital calendar corresponding to a user. The triggering calendar entry occupies a time that is inconsistent with data corresponding to the first digital calendar. The code is executable by the processor to synchronize the triggering calendar entry with a second digital calendar corresponding to the user without synchronizing each calendar entry of the multiple calendar entries.
