Droid X Family Calendar & To Do List App?

'K. Got the latest Droid @ Verison. I NEED a calendar app that includes holidays, to do lists, etc. I'm a mom and I have a couple of small bizs that a heavy with dates.

I've been a Day Timer gal for 10 years.

Who can show me an app you love? Help, Help, Help!

I can't deal with the preloaded My Calendar. I've searched Market Place and I can't find what I'm looking for.

But then again, I don't understand sh*t.

What do you like? What works for you?

I'm a mom with multiple schedules; need holidays, birthdays, a to do list and pretty much the same stuff I had with my paper Day Timer.

I respectfully throw myself on your floor and beg for your recommendations.

Thanks!!!!
