They're celebrating March 8th, International Women's Day, but two weeks later

Just today, my wife, along with a group of other sisters, decided to organize a group dinner and go to a restaurant, leaving their husbands at home. Coincidentally, everything was organized today, March 8th, International Women's Day. As always, Jehovah's Witnesses say they don't celebrate like worldly people, but then they always find a way to do as they do. The important thing is not to do it on the same day.
