I think that I would periodically (every 15 mins) create a queue of the pending
reminders for the next interval in order they occur and then every minute, examine the
top entry and compare it with the current time, and, if necessary, pop the reminder
off and send it. This way you're only hitting the database every 15 minutes and the
queue would be in memory. Hope this helps.

Subject: Re: Reminders for web based Calendar
I have to give reminder to his email or a Mobile...so
I basically should be having a Calendar server running
which can keep track of all these reminders...
Lets take a case :
User wants a reminder on Wednesday 5.30 pm about
something....and he sets the reminder today....
so the Calendar server should be checking the database
..lets say every one minute
but that will be too much...so what are the other
techniques???
Please help...this is really urgent
