As a general remark: "a date" is not a standardised (or standardisable) data format. You can search (as RudiC suggested) for this regex, but be aware that it doesn't search for "a date" but for two digits, followed by a slash, followed by two more digits, followed by another slash, followed by four more digits.
In most cases, a string matching that will be a date indeed, but it might be something else either. Further more, this: 1/1/2016 is perhaps a date too, but wouldn't be found by the regex. On the other hand you could remove the restrictions RudiC has perhaps put in for safety and simplify the regexp to:
but in this case it would find a "date" in the following sample text, which denotes the common way in Austria to tell the street number, apartment number and the floor on which it is located:
Bottom line is: you will have to be careful to watch if what you place as restrictions to dates will lead to all the correct things being found and all the incorrect ones being thrown out. But this is a slippery slope and there is no final algorithm which separates all "dates" from everything "not a date".

nqs2pbs(1B) PBS nqs2pbs(1B)NAME
nqs2pbs - convert NQS job scripts to PBS
SYNOPSIS
nqs2pbs nqs_script [pbs_script]
DESCRIPTION
This utility converts a existing NQS job script to work with PBS and NQS. The existing script is copied and PBS directives, #PBS , are
inserted prior to each NQS directive #QSUB or #@$ , in the original script.
Certain NQS date specification and options are not supported by PBS. A warning message will be displayed indicating the problem and the
line of the script on which it occurred.
If any unrecognizable NQS directives are encountered, an error message is displayed. The new PBS script will be deleted if any errors
occur.
OPERANDS
nqs_script
Specifies the file name of the NQS script to convert. This file is not changed.
pbs_script
If specified, it is the name of the new PBS script. If not specified, the new file name is nqs_script.new .
NOTES
Converting NQS date specifications to the PBS form may result in a warning message and an incompleted converted date. PBS does not support
date specifications of "today", "tomorrow", or the name of the days of the week such as "Monday". If any of these are encountered in a
script, the PBS specification will contain only the time portion of the NQS specification, i.e. #PBS -a hhmm[.ss]. It is suggested that
you specify the execution time on the qsub command line rather than in the script.
Note that PBS will interpret a time specification without a date in the following way:
- If the time specified has not yet been reached, the job will become eligible to run at that time today.
- If the specified time has already passed when the job is submitted, the job will become eligible to run at that time tomorrow.
PBS does not support time zone identifiers. All times are taken as local time.
