Each month we need the identities of employees who joined the company 3
months and one year ago.

It is nonsense to go through the list manually, but I can't find a way to do
it automatically. Ideally, I would end up with a separate spreadsheet, or
even a separate section of the existing spreadsheet, that contains the names
and other data from persons who match the criteria:

Name, Hire Date, Job Title, Department, month FOR Records WHERE (Month of
Hire Date) = (This Month - 3 months) OR (Month of Hire Date) = (This Month
-12 months).

And collects them all in a nice, tidy box I can ship to the relevant
managers. Sorted by Department. Lightly scented with lavender.

Seems simple, but is beyond me. I'm a real newby at this, so if you use
abbreviations, I am guaranteed not to understand them.

Thanks in advance.
