Same calendar as January 2039

January always has 31 days, so any January that starts on a Saturday has the same layout. January 2039 matches January 2000, 2005, 2011, 2022, 2028, 2033, 2050. A printed calendar from any of those years can be reused for January — but check holidays such as MLK Day, which always lands on the third Monday.
