|For programming into the VCR on January 1st for correct day and date, what years in the 1900s have the same calendar as the year 2000? An identical calendar must, like 2000, be a leap year starting on a Saturday. Leap years occur every four years, and every seventh leap year starts on a Saturday, so calendars like 2000 occur in 2000 - 28 = 1972, 1972 - 28 = 1944, and 1944 - 28 = 1916.|
