A total of four variants are possible: 1. daily alarm, sounds at the same time every day, 2. date alarm, to think of birthdays, for example, 3. monthly alarm, sounds at the same time on the same day every month, 4. alarm for every day of a particular month.after you stop the alarm signal, it sounds again automatically after a few minutes. Once set, the automatic calendar always shows the correct date. The time display can be set to either 12 or 24 hour format. In 12-hour mode, a "p" in the display indicates the second half of the day, i.e. 12 noon to 11.59 pm.
