No, it can be the same irule.

when RULE_INIT {
    array set static::timerange {
        Sunday {}
        Monday {}
        Tuesday {"02:00" "14:00"}
        Wednesday {}
        Thursday {}
        Friday {}
        Saturday {}
    }
}
 
when HTTP_REQUEST {
    if { ([string tolower [HTTP::uri]] contains "/contractor/") } {    
        set now [clock seconds]
        set current_day [clock format $now -format {%A}]
        set start [lindex $static::timerange($current_day) 0]
        set end [lindex $static::timerange($current_day) 1]
        if {($start ne "") && ($end ne "") && ($now >= [clock scan $start]) && ($now < [clock scan $end])} {
            set denied 0
        } else {set denied 1}
        unset start end
    } else {set denied 0}
 
    if { $denied } {
        HTTP::respond 200 content "Not Authorised! Contact AdministratorNot Authorised! Contact Administrator..."
    } elseif { [active_members [LB::server pool]] == 0 } {
        HTTP::respond 200 content "<content>"
        unset denied
      } else {pool POOL_443}
       unset denied
}

Cheers,
