ClassicTVHits.com is now posting times for M*A*S*H to air on Hallmark. In addition, Hallmark has added a M*A*S*H page to their site, although it has no details. As of Tuesday, September 2nd, M*A*S*H will be airing from 3:00PM to 5:00PM, and then again from 10:00PM to 12:00PM. It is unknown if these two-hour blocks will be the same episodes shown twice.
On September 1st, the day Hallmark acquires M*A*S*H, they will be airing the show from 6:30AM until 1:00AM, as a Labor Day Launch Marathon sort of thing. For the next three days, the 2nd through the 4th, two-hour blocks will be aired from 8:00PM until 10:00PM, then the 10:00PM to 12:00AM showings will be aired.
