Dear Mr. Munster,

     On February 25, 1948,¹ the communists seized Czechoslavakia and installed a puppet ruler in Prague.

     In 1953² television station WKGB began broadcasting from Cambridge, Massachusetts,³ and August 31⁴ was the date of their first broadcast.

     Those are the dates, years, and months of those events.  I hope I've answered your questions to your satisfaction.

                                                                         Sincerely,

                                                                        Mr. Knowzit

²The year alone is not set off in commas.

³The state is set off in commas to separate it from the city.
