Need formula or Macro Help

[Atomic]

Would appreciate if someone can help me create a (Macro or Formula) that would.

Below when I enter:
07-01-01, 07-04-01, 07-07-01 or 07-10-01

Turn into below:
07-I-01-01, 07-II-04-01, 07-III-07-01 or 07-IV-10-01
(The year needs to be flexible since I must use this for the years to come
like 2008-2020, something like that)

Something where the quarters should result automatically to the month of
each Quarter.

The quarters begins: 01-Jan-Mar, 02-Apr-Jun, 03-Jul-Sep, 04-Oct-Dec

Here is a crude solution:

If the date was entered as text in D5 in the format YY-MM-DD, the following
formula in another cell will return the result you want:

=LEFT(D5,3)&CHOOSE(MID(D5,4,2),"I","I","I","II","II","II","III","III","III","IV","IV","IV")&RIGHT(D5,6)

This is all one formula. It may wrap in my reply because of its length.

Hope this helps,

Hutch
