Something like this:

Code:
awk -v d=$day -v m=$month '
if( $2==d && $1==m ){
  print "Yes"
}
else {
  print "False"
}' syslog.txt

Or just:

Code:
awk -v d=$day -v m=$month '($2==d && $1==m){print "Yes";next}{print "False"}' syslog.txt

shtool-mdate

SHTOOL-MDATE.TMP(1)					      GNU Portable Shell Tool					       SHTOOL-MDATE.TMP(1)

NAME

       shtool-mdate - GNU shtool pretty-print last modification time

SYNOPSIS

       shtool mdate [-n|--newline] [-z|--zero] [-s|--shorten] [-d|--digits] [-f|--field-sep str] [-o|--order spec] path

DESCRIPTION

       This command pretty-prints the last modification time of a given file or directory path, while still allowing one to specify the format of
       the date to display.

OPTIONS

       The following command line options are available.

       -n, --newline
	   By default, output is written to stdout followed by a "newline" (ASCII character 0x0a). If option -n is used, this newline character is
	   omitted.

       -z, --zero
	   Pads numeric day and numeric month with a leading zero. Default is to have variable width.

       -s, --shorten
	   Shortens the name of the month to a english three character abbreviation. Default is full english name. This option is silently ignored
	   when combined with -d.

       -d, --digits
	   Use digits for month. Default is to use a english name.

       -f, --field-sep str
	   Field separator string between the day month year tripple. Default is a single space character.

       -o, --order spec
	   Specifies order of the day month year elements within the tripple. Each element represented as a single character out of ``"d"'',
	   ``"m"'' and ``"y"''. The default for spec is ``"dmy"''.

EXAMPLE

	#   shell script
	shtool mdate -n /
	shtool mdate -f '/' -z -d -o ymd foo.txt
	shtool mdate -f '-' -s foo.txt

HISTORY

       The GNU shtool mdate command was originally written by Ulrich Drepper in 1995 and revised by Ralf S. Engelschall <rse@engelschall.com> in
       1998 for inclusion into GNU shtool.
