Here are the tips she gave me.

Cups = Days
Wands = Weeks
Pentacles = Months
Ace-10 = one to through ten
Princess/Page = eleven
Prince/Knight = twelve

Any Sword = undetermined, up to you
Queen = undetermined, up to you
King = undetermined, up to you

Major Arcana = NOW! This is an ongoing psychological or spiritual process.

I would add that the Major Arcana are generally indicators of something that is outside of our normal sphere of control.
