cron to get executed on 2nd and 4th saturday of every month

Hi ,
i need to reboot a server during 2nd and 4th saturday every month. i have come up with the below cron

Code:
 
30 17 8-14 * * if [ `date +\%u` -eq 6 ] ; then /rebootscript; fi # to reboot every second saturday
30 17 22-28 * * if [ `date +\%u` -eq 6 ] ; then /rebootscript; fi # to reboot every fourth saturday

I am wondering why it does not work this way

Code:
 
30 17 8-14 * 6 /rebootscript
30 17 22-28 * 6 /rebootscript

Please help me in understanding this.

NNSTATS(1m)															       NNSTATS(1m)

NAME
nnstats - display nnmaster collection and expire statistics SYNOPSIS
nnstats [ -lt ] [ -d month day ] [ -m month ] [ logfile ]... DESCRIPTION
nnstats will extract the collection (C) and expiration (X) entries from the log file and calculate total and average number of articles, groups and elapsed time per day, per month, or for the duration of the whole log file. Normally only a summary for the specified period is printed. If -l is specified, the statistics for each day in the period is also printed, and if -t is specified the summary is not printed. Normally the statistics is collected for all days in the log files (or the current log file if one is not specified). If "-m month" is specified, the statistics for that month is calculated. The month is specified in normal date notation, i.e. a capital- ized three letter abbreviation like Jan, Feb, ... If "-d month day" is specified, the statistics for that date only is calculated and printed. FILES
../Log The log file SEE ALSO
nn(1), nnusage(1M), nnadmin(1M), nnmaster(8) NOTES
If nnmaster is run with options -LCX, nnstats will not work, because the necessary entries are not written to the log file. AUTHORS
