Does the Sleeper Simulant Quest always open on the 7th?

I realise this is more of a #Help question but in the interest of developers wanting to build a calendar into their apps I've put this here. https://m.reddit.com/r/DestinyTheGame/comments/49ciyc/todays_the_7th_go_start_the_sleeper_simulant_quest/ I've been wondering this myself since I have siblings and friends who missed the initial window of the event going live. If the 7th reset of each month will always trigger the first quest to show up in the Director, will this continue to be the case for the foreseeable future? It would be great that timed activities like this had a place somewhere in the APIs (once they are declassified of course) we could pull from. Perhaps there already is?
