The ability to see all of my event information in one place was very helpful! I never knew what time an appointment would be until it showed up at that point so this helped me keep track more easily than before when i had multiple calendars open with different appointments spread out over several days/weeks ago (or even years). Also being able to check availability without having another calendar open just made things easier since sometimes you only need 1 or 2 minutes notice if something changes suddenly like last minute cancellations etc - not enough hours per day if your looking after everything yourself :) Great way to schedule meetings between employees as well too which saves tons of paper work and emailing back-and-forths with meeting times ect.
