Here is two options. Either place the restriction in whatever user
database you are using, only keeping the account enabled at those dates,
or build the restriction using acl's in squid.conf.

Now, Squid acls as such is a little limited in this regards as it
doesn't support dates, only days of the week and time. But It's
reletively trivial to extend with an external acl evaluating the time..

Example external acl helper for date checks. Used like

external_acl_type datecheck /path/to/datecheck.sh

acl user_a_dates external datecheck startdate enddate

where startdate and enddate is given like YYYYMMDD where YYYY is year,
MM is month and DD is day.

#!/bin/sh
while read start end; do
        today=`date +%Y%m%d`
        if [ $start -le $today && $end -ge $today ]; then
                echo OK
        else
                echo ERR
        fi
done

Depending on how the timezone is configured on your server you MAY need
to add a TZ variable in the beginning of the script defining your
timezone. But normally not needed.

TZ=yourtimezone
export TZ
