If you have a public Yahoo calendar, you can share it with visitors to your website. Any updates to the Yahoo calendar are automatically shown on your website. (You can't change the calendar from your website; you'll have to do that within your Yahoo account.)
There are two parts to connecting the calendar to your website. This part explains how to copy the necessary code from your Yahoo account. The second part explains how to Display a calendar on my website.
Note: Be sure the calendar you select includes future events, or Bytique will tell you that it couldn't find any events in the calendar.
Note: Be sure you use the ICS link. Bytique only recognizes ICS as a valid Yahoo calendar to import.
