I remember sometimes she announced it even prior to the albums (RnRC and CdM tours), but usually we get announcements between late December and early February.

A BEST LIVE was announced on February 1st and started on April 13th, while CdM Tour was announced on December 29th/30th also starting at April, on the 11th... I see it as safer to safer to say when she usually tours (between April and July) rather than when she announces the concerts, but then 2014 had Premium Showcase which had a different schedule and concept. Still, I risk saying June is a safe bet, cause PSC had almost all its dates on June and it's in her usual touring months.
