@DoubleAA, They started in with the "Shoshanat Ya'akov" tune in my shul already this past Shabbat, at Birkat Hachodesh. I think the first day of Rosh Chodesh is fine. Note that in the post, I specified tonight at sundown as the start point for this year. Note also that as I said above, I think that we don't need to enforce the time limits with very close precision. We just want to keep this feature reasonably in check. —
