aligning colon

[JRaul]

I have created a 1 page document ...... the following is a example just to show how the colons are not aligned.My document the colons are mis-aligned and i do not know how to align them up perfectly.

Time of the day : #####
What is the date today : #####
How many weeks to christmas day : #####
Is today cold : #####

1. How do i lign up the Colons so they are all in a straight line going down the page
2. I`ve already created my document.Can i go back and lign up all the colons perfectly or do i need to set all this up before creating my document?

Cheers
Jason
