I have four calendars I manage on a daily basis to organize my time and schedule: Full time job When I schedule an appointment on my personal calendar, I now need to go block off time on the three other calendars to ensure I don't get double booked. Or when I get invited to a meeting at my full time job, I need to block off that time on my consulting calendar and the family calendar.
At the time of writing this article, I have six connections setup between various calendars in Calenderio.
You can see above that I have each calendar setup as a two-way sync, meaning events created on the Life calendar are sent to the three other calendars as well.
