Answer

Because YK is a major holiday and not a minor fast, we treat it the same as other major holidays. To find fast start and end times, use the Candle lighting event that corresponds to Erev Yom Kippur, and the Havdalah event immediately following Yom Kippur

All other fasts contain "category":"zmanim","subcat":"fast" - so I can find when fast begins or ends.
Yom Kippur does not contain this information
