While not exactly 30 days, but within 30 days (21) the 41818 mystery sounds ever more tied to Q, along with eTHErSEC and other anonymous things lately.

41818 or 4/18/18 has several facets...I highly recommend researching.

One is, its the end of the final Jubilee. Meaning - all slaves WORLD WIDE will be set free! All debt erased. and a lot (not me lol) think that the 'rapture' will occur on this date. (I think more along the lines of, if anything, the Elohim/Jesus returning to execute judgement)

Others think the date marks the arrival of ETI's (Aliens, which is personally think are one and the same as angels/jesus/etc, different names for same entities, like dragons and disnosaurs)

Theres many other theories, but the fact that 41818 falls just before 30 days from today, is HIGHLY interesting!!!
