Portable UK's Kalender 2.2.2 offers users a useful calendar with lots of options for the appended events. UKs Kalender is a calendar with a nice month view, advanced features for repetitive events, snooze function and a plethora of other capabilities.

Major Features:

1. Automatic saving: Any changes to the database are automatically and immediately saved to disk. On every program start, a backup copy of your data file is created.
2. Unlimited Undo and Redo: Most changes can be undone and also repeated.
3. Minimize to the system tray: "UKs Kalender" minimizes into the system tray (the area next to the system clock).
4. Network support: "UKs Kalender" supports a shared event file, where every user can enter events thatll show up in each other users calendar. For using the network functions it is neither required to install special server software nor to keep the computer with the shared event file permanently running. "UKs Kalender" will synchronize the local event file as soon as the shared event file is accessible.
5. Repeating events: There are lots of possibilities for entering repeating events, e.g. hourly, every three days, monthly, every first tuesday of the month or even every friday the 13th.
6. Forewarn time and snooze function: Each event can be assigned a user defined forwarn time in the range from one minute to several weeks. In the reminder dialog you can enter a time after that youll be reminded again. Alternatively you can choose to be reminded again a certain time before the event.
7. Multi day events: Events can have a duration from one minute to several days (or no duration at all, but just a start date).
8. Event categories and templates: Events can be organized into categories, e.g. "Doctor", "Meeting", "Party" and so on. Each category is assigned a template of settings, including repetition rate and forewarn time.
9. Acoustic reminders: You can choose to be reminded of an event with a WAV file of your choice.
10. Event driven program execution and document opening: Documents or programs can be attached to an event. This is very handy for e.g. regular backup purposes.
11. Marking and hiding events: Special events may be either color marked or hidden.
12. Four event views: Events can be displayed in week-, fortnight-, monthor year-view.
13. Tooltips for events and to-dos: If you stop the mouse over a calendar date or a todo, extended info is shown for the events and to-dos.
14. Alarms can be deativated: Alarms may be deactivated all at once, so your game, film etc. wont be interrupted.
15. Highly configurable display for events and to-dos: All views can easily be configured to present the information just the way you want.
16. Search and filter functions: You can search for and filter out your events using keywords, categories, event states or date ranges. The filter function directly affects all output functions, so you can easily create e. g. a calendar only containing birthdays. Filters can be named and saved for later reuse.
17. Clipboard support: Events and todos can be copied to the clipboard and may be pasted back to any word processor or "UKs Kalender" itself.
18. Export to HTMLand CSV-format: Events and to-dos can be exported to HTML-format in different views. With this you can easily print your dates and todos. Export to CSV-format allows the transfer of your data to a spreadsheet program. All activated filter options are applied to the output.
