Extract Certain Characters From A Text String

[Rick Rothstein]

Sorry. I was trying to be as brief as possible. Here are some samples of what my data looks like:
Heartsaver CPR and First Aid Course April 13th, 2013 [example without hyphen]
BLS Certification 2013 - 8:00am - 11:00am, April 12th 2013
PALS Renewal Course -- 9:00am to 5:00pm - April 4th, 2013

In looking this up, I just realized that some of my data is NOT separated by a hyphen so I am now in a bit of a pickle.

Some questions to help narrow things down some more (please answer each one of these as I have asked them for a specific reason)...

1. Will the last part of your data always be a time and/or date (with no other text following them)?

2. Could your data ever have the time only with no actual date (I'm guessing no for that, but figured I should check just to be sure)?

3. When both the time and date are present, will the time always be shown before the date?

4. Could your data ever look like this... "Descriptive text 8:00am - 11:00am, April 2nd 2013"... where there is a hyphen but it is not for separating the information from the time/date?

5. Will your times always have an am/pm tag on them?

6. Will the am/pm tag always follow the time without a space character separating them (as you show in your examples)?

7. Will the month name always be a full month name or could it be abbreviated sometimes (such as Apr 23rd 2013)?

8. Will the time and/or date always have a space character adjacent to them? What I am trying to find out here is whether you could have data that looked something like any of these...

Descriptive text (8:00am - 11:00am) April 2nd 2013
Descriptive text [8:00am - 11:00am] April 2nd 2013
Descriptive text /8:00am - 11:00am/ April 2nd 2013
and so on...

9. And Admin's implied question... will your data always have a time and/or date in them (with a tip of the hat to my first question) somewhere?
