Patrick O'Brian's Aubrey and Maturin novels say that in the early 1800's the Royal Navy used a 13 month, 28 day calendar.

Anybody know the names of the months, especially the extra month? Google searching isn't finding it but there is a lot of babble about hippie calendars.

Also, the RN's day started and ended at local noon, not at midnight. They shot the noon day sun every day they could so they could determine the local noon.

Turn the glass and ring the bell.

Looks to be based on the "Old English" 13 month lunar calendar.

The number of days in a solar year isn't an exact multiple of the number of days in a lunar cycle, so there are 12-and-a-bit lunar months in a year. As a result, the English months moved around in relation to the solar year. Every so often an extra month was added at Midsummer, making a 13-month year, to keep the months aligned roughly with the seasons.
