+ A 'month of Sundays', connoting a long period of time and often regarded as the period of time for someone else to perform a task that you consider to be straightforward, is literally 211 days (7*30 + 1). The first Sunday is to occur on the first of the 211 days and the 31st Sunday occurs on the 211th day. [Green]

+ The only 3-digit prime such that the sum of any two of its digits is also prime. [Green]
