there is alot way to do so....
here is 1 of the way.
On<weekday><hou<minute>:
This will execute when the server clock hits the specified date or time. Hours
and minutes are given in military time. ('0105' will mean 01:05 AM). Weekdays
are Sun,Mon,Tue,Wed,Thu,Fri,Sat. Months are 01 to 12, days are 01 to 31.
Remember the zero.
beside..you can also use this way..check for what day it is then only check for time to run event..
