"the morning of the 5th Feb 1745, in the Gregorian calendar, would be noted as the 4th February in a British ships log."

The naval calendar was AHEAD of the civil calendar. The naval day February 5, 1745, ran from noon on February 4 in the civil calendar to the noon on February 5. The morning of a civil day is found under that date in a British log, but the afternoon is found in the next day. When times are noted in logs and journals, PM times are given first, AM times follow. Events that occurred on the morning of February 5 in the calendar used by the French navy and the Compagnie des Indes Orientales would be found on the morning of January 25 in British naval officers' logs, journals, and reports; the afternoon of Gregorian February 5 would be referred to as "January 26" in British naval records. As far as I can tell from the French documents I have seen, the French navy and merchant marine used a midnight to midnight day, not a noon to noon day.

Just to clear any possible confusion.

The date of 25th Janusary 1744 is from an English source, England used the Julian calendar until 2nd September 1752. The Julian calendar was at this time 11 days behind the Gregorian calendar used in most of europe and the first day of the year was 25 March not 1st January, hence the 1744/45 date display.

This means that the 25th January 1744 is the same day as the 4th February 1745 in the Gregorian calendar.

An added complecation is that the British navy's official day did not start until noon, so the morning of the 5th Feb 1745, in the Gregorian calendar, would be noted as the 4th February in a British ships log.

I have added a converted Gregorian date after the Julian one to try and help.

Also a look at the  Definitions page might help.

La capture au détroit de Banca de ces trois vaisseaux français n'a pas eu lieu le 25 janvier 1745 mais le 5 février. Voir le site pierre-poivre sur le web avec les mots Maverick Deptford Preston. Plusieurs documents en référence.
