Why two o'clock? The thinking goes it's late enough that most people would be at home, with few bars and restaurants being affected. In addition, it prevented the date from switching to yesterday; it would be confusing if, say, we changed the clocks at midnight back to 11 p.m. The time is also early enough that the clock-hand change occurs before early shift workers and early churchgoers might be impacted, according to the WebExhibits, an online museum.
