Could not manage my days without it

I’ve been using BusyCal for so long (years), that I can’t remember what the iCal frustrations/headaches/limitations were that drove me to seek out another calendar program. But BusyCal addressed all of my woes, and does everything you’d want in a calendar, and more. Customer support is excellent, too.

Serenity too about BusyCal 2, v2.6.2
