Editorial note — Chapter XXV · Charles I. And Cromwell. Captivity, Trial, And Death Of The King.
Reading edition
[Footnote 1: The day of the death of Charles I. is celebrated on the 30th of January, because England had not yet adopted the Gregorian Calendar. The 30th of January, 1648, corresponds with the 9th of February, 1649.] [Transcriber's note: From Wikipedia article "Gregorian calendar"; "In common usage, 1 January was regarded as New Year's Day and celebrated as such, but from the 12th century until 1751 the legal year in England began on 25 March (Lady Day). So, for example, the Parliamentary record lists the execution of Charles I. on 30 January as occurring in 1648 (as the year did not end until 24 March), although later histories adjust the start of the year to 1 January and record the execution as occurring in 1649.]
