Common year starting on Sunday
This is the calendar for any common year starting on Sunday, January 1 (dominical letter A) or for any year in which “Doomsday” is Tuesday.  Examples include years 1978, 1989, 1995, 2006, 2017, 2023 (the current year), and 2034 in the Gregorian calendar. I.e. includes 2045 and 2051 which is immediately preceded from the previous common year type. After the first other year mentioned above and this year type will be preceded onto year starting on Monday but common. While after 2051, in other words will also be another year starting on Monday but it’s leap already. The “spank” date also occurs with year such as Saturday the 19th where the 19th day of any month falls on a Saturday. However, we have only one occurrence of this date, which only occurs in August. While the other thing, is “Wednesday the 19th” but occurs twice this year, in April and in July. One more note about Saturday the 19th: occurs twice in common years starting on Saturday plus one more in February so the two occurrences are in March, and in November. As far as known, leap years starting on Friday shares this same thing.
