Lu,
Too bad you weren't at the Nav Weekend at Mystic Seaport in 2008:
A Brief History of the Nautical Almanac
Planetarium Classroom. In celebration of the 50th anniversary of the modern Nautical Almanac, Frank Reed will do a presentation on the history of the various almanacs used by navigators in the past 200 years focusing on the roundabout path leading to the Nautical Almanac we have today.

My previous post made me think: What is the history of the Nautical Almanac? How long has it been produced by the US? By the UK? What did mariners use as a nautical almanac before these publications became available? I assume that as soon as chronometers (and/or lunars) became available (mid- to late-1700s) navigators suddenly needed to accurately know star positions any time, any day, across the year.
When Harrison's first practical chronometer was taken afloat to Jamaica, by what method did the British government representatives determine that it was only 5 seconds off after a month at sea?
