This site is a free service to all contesters and interested parties. It is non commercial and exclusively dedicated to ham radio HF contests and similar events.

The centerpart is the Ham Radio Contest Calendar which is built up of 4 single Google Calendars. You can sync them with your own calendar application, embed them into your own website or just view 'em here.

How to use

The calendars are seperated by mode. There are

  • CW Calendar
  • Phone Calendar
  • Digital Calendar
  • Mixed Calendar
The mixed one contains all those contests which offers several modes, e.g. CW and Phone. Each contest is assigned to only one calendar. No contest is duplicated.

In the upper right corner you can switch the views between agenda, month and week (1). There also is the calendar list (2). Click on the down-arrow next to the Agenda button to choose the calendars you need. In the upper left corner you find the navigation (3). Depending on the choosen view you can switch between days, months, weeks and so on. 

The calendar entries (4) look like this: 

ARRL IARU HF World Championship [CW,SSB | 160,80,40,20,15,10].

That follows the scheme 'name of contest [Modes | Bands]'. If a range is given, e.g. 160-10, that means the contest runs from 160m to 10m excl. WARC.

Click on an entry to see the link to the sponsor's website (4). You need another click on 'more details' to get the clickable version of the link. Some of the official rules might not be in English though the contest is open to all. Use Google Translate or something like that then :)

Be aware that I have no influence on the content of all these external pages. If I see any inappropriate stuff I remove the respective link of course. But there is no guarantee!

How to search

Unfortunately there is no way to search through the Google Calendar at this time. But usually you can search through it after you have synced it with your own calendar application.

How to sync

The added value of the Calendar is that you can sync (read only version) it with any other calendar product which supports the Ical format on your desktop or mobile. So you have always the up to date contest calendar with you. 

Here are the calendar addresses you need for that. Copy and paste the desired addresses into your calendar software. Refer to the help section of your product if necessary.

CW Calendar - Ical address

Phone Calendar - Ical address

Digital Calendar - Ical address

Mixed Calendar - Ical address

How to embed

Paste the code into your website to embed the calendar. Play around to modifiy width, height, colors etc.

<iframe src=";mode=AGENDA&amp;height=600&amp;wkst=2&amp;bgcolor=%23FFFFFF&amp;;color=%23182C57&amp;;color=%2342104A&amp;;color=%236B3304&amp;;color=%238C500B&amp;ctz=Etc%2FGMT" style=" border-width:0 " width="800" height="600" frameborder="0" scrolling="no"></iframe>


Once a month I review the calendar entries of the next 4 to 6 weeks and bring them up to speed. Anyway it may be that some data is not right. That for instance may occure when a contest sponsor does modification short before the event.

If you are a serious contester you should visit the sponsor’s website betimes to verify the start time of the contest in which you want to participate.
