Thanks to Google archiving the old Providence News newspaper, it appears WEAN came on the air June 14th 1922 (Flag Day). I haven't found an earlier listing for WEAN going back to June 2nd which is what the Providence Journal Almanac had reported. It appears regularly scheduled programming started @ 3P that day.
