To find a specific contest use the Google Calendar or the search field. In case of using the Google Calendar you will get the rules by clicking on an entry and then on the link on the details view.
Use the Google Calendar to copy events into your own Google Calendar.
You also may import the calendar, which actually consists of 4 separate calendars, into Outlook, Thunderbird etc. pure cw contests | pure phone contests | pure digital contests | mixed (contests with several modes).
I am an active contester and I want to keep the calendar up to date. If you notice missing or wrong date give me a note.
