Hammer & Screwdriver awk works by default with either tab or space delimiter
So, if your input file was slightly different, you might not get your desired results with a 'plain' awk. See below where there is a single space between the month and a number:

Code:
> cat file66c.tsv
13      Oct 1   Joe     smile
18      Jan 2   Linda   laugh
11      Nov 3   Vets    march

> cat file66c.tsv | tr "\t" "~" | cut -d"~" -f2
Oct 1
Jan 2
Nov 3

> cat file66c.tsv | awk '{print $2}'
Oct
Jan
Nov
