Pulling Specific Data From Random String

I have random comments in a column of cells of which I'm searching for a specific string of characters that may be contained in each cell. I want to pull 2 pieces of data from this specific string and place the data in 2 other cells in the same row.

Sample comments in cell 'N1':


..... blah, Appt: Friday; 12/4; night drop off. blah, blah....
Sample comments in cell 'N2' (and so on and so on):


.....blah, blah, Appt: Thurs; 12/3; 12:30PM. blah, ....

The specific string in the above examples will always begin with:


APPT:
Then the key elements found directly after the 'APPT:' are:


Thurs; 12/3; 12:30PM.

(which are the)

DAY; DATE; TIME.
These elements will be always separated by the semi-colon ';' and the string will always end with the period '.'

I need a pair of formulas to be in col 'J' & 'K' to extract the DATE and place it in column 'J' and the TIME and place in column 'K', both in each same rows.

So, from the 2 above samples I would need the following:

in Cells:
J1 - 12/4 ....... K1 - night drop off

J2 - 12/3 ....... K2 - 12:30PM

I've been trying to come up with a formula using a combination of FIND() & MID(),
