Hi, common RTC chip offers one or two alarms when RTC is waking up the AVR to do some process. If I understand well, no more then 2 alarms are possible. Do you have any idea how to manage more alarms (single alarm times), let's say 10 or 20?
I am thinking about preparing an array of alarm times and when the RTC alarm time is out, replace it with next one from the array.
Please help with it. Thanks.

One option would be to not put the Arduino to bed and handle the alarms there.
And indeed, another option is to just load the RTC with the next (most nearest) trigger moment and repeat when the alarm went off.
I agree. So there are not more effective solutions for that I thinks.
I think it's a pretty efficient solution. Do you mean lazy? 
Yes, that's a good solution 
It seems there is not any other better way... I need my device to be asleep so the other one is not acceptable for me.
