Good Menubar Calendar

The Mac menubar is a perfect place for a calendar, and Callendar 366 fits the bill nicely! It's priced right, and has natural language event and reminder entry. Overall a good app, and it's been well supported with updates and new features so far.

I do hate how it ALWAYS loads without any events on first run after starting the app, after 1-3 seconds it populates with events. Seems something that could be done upon startup before the UI loads for the user.

Another Winning Version!

This calendar app is the cleanest and quickestt available. If you liked the early version(s) of Fantastical, this is for you. In this version they add more views and a cleaner interface, and yet retain the simplicty and speed. I SO WISH I could also use this on my Windows PCs in a simlar fashion - it just works quick and easy. Natural language input, varied views, quick setup, etc. So good!

Great, but something has changed...

I've been usingthis app since it came out. I 've always thought it was the perfect calendar app. Now I don't know if this feature changed in a recent update or I'm just missing something. You used to be able to SET REMINDERS for an hour, 2 hours, 15 mins before an event, now you can only set it to a specific time on that date. If the developer sees this, can you please let me knon if I'm missing something or add that feature back.
