Was thinking along same line but if you base on 2018, the next in the series is 2019-10-07. Some other keys dates in the series are Independence Day and 9/11. 

Would be interdasting to see if news unlocks, POTUS twats correlate, or Q posts habbened on any these dates. 

2018-05-19
2018-06-11 <- US 11th = SING12th
2018-07-04 <- coincidence?
2018-07-27
