Day-O is a simple menu bar clock replacement with a simple calendar for your Mac. It’s free, as-is (which means I’m not providing support, taking feature requests, addressing perceived inadequacies or releasing the source code). Here’s how it came to be:
My late upgrade to Lion was relatively painless. The only casualty was MenuCalendarClock. It somehow clobbers the Dictionary shortcut key command and gesture which I use daily (if not hourly). I thought I could live without MMC. I don’t use any calendar apps so I was just using the free version for the simple date icon and convenient fly-out calendar. I thought the system menu clock would suffice. Really, how frequently did I use the fly-out calendar?
Turns out, quite a bit. I tried a few replacements but couldn’t stand any of their date icons. MMC developer Objectpark seems to have gone quiet. Fortunately, as I quipped on Twitter, I’ve “never met a wheel I didn’t want to reinvent.”
I may or may not have had this YouTube video on repeat in the background the entire time.
Update: Day-O does not work with Dark Mode because the stock calendar widget used by Day-O does not appear to support changing the table cell text color. I hear Mowglii’s Itsycal works fine.
