Alarm date and time

You can choose the alarm to sound once or to sound it periodically. For each option, different settings can be specified.

• Sounding the alarm once
• Sounding the alarm periodically

Add
The 'add'-option is a setting which can be used with all of the above options. It is meant to be used for the following purposes:

• If you want to make a correction to the specified date. For example: you want an alarm to go off 3 days before the end of each month. Make the alarm sound periodically, set the period to 1 month, set the 'Include' date to the first of the month, and set the 'add'-option to -4 days (4 days before the first of the next month).
• If you want an alarm to sound after a certain amount of time from now. Set the 'once' date to the current time and specify the amount of time to add.
• If you have an alarm group with birthday alarms, you can set the date to the date of the persons birthday. Of course, you'll want to be warned before the person's birthday, so you set the 'add'-option to -1 day. If you later decide you want to be warned 3 days in advance, all you have to do is select all birthday alarms, choose 'properties...' from the 'alarm' menu, set the 'add'-option to -3 days and click 'Ok'.

Note that the 'add'-controls do not affect the specified period (between ... and ...) in which a periodical alarm is active.
