The end dates should be listed on the "news" items of the individual heroics and the end time should be exactly 24 hours before the heroic loot chest ends. Heroic modes didn't get a start date announcement in the past, so them being listed on the monthly news item (which ironically doesn't seem to stay around for the whole month...) is already an improvement.
