This app is suitable for calendars according to the ICS standard RFC 5545/5546, which is used by most computer programs. This is the prerequisite, so that you can also use your calendar from the PC with Outlook, Lighting or other software. This calendar inherits the following functions: - Date Overview All appointments are displayed time-dependent. The list can be searched. The list is kept on the iPhone and can be stored and loaded externally. Appointments can also be transferred from the iPhone - Monthly Overview Monthly overview helps navigate through calendar dates quickly. Appointments additional are listed separately. An overview of appointments of the day couldt be called up on the screen. - Date Appointments can include date and time or just the date. These can be stored with or without time zone. So, for example the date New Year should be used without time zone as the year actually begins on earth at different times. In contrast, a birthday with the time zone should be deposited, in which the jubilarian lives. Thus, at the time of congratulation nothing goes wrong. - Series date One-off and serial appointments can be generated. A recurring event is controlled by a rule by which the repetitive appointments are generated. These rules fulfill the standard. So you do not have to dive deeper into the rules, as most common rules could be created by key combination.
