Calendars for years before 1776 are not available since before that date not all countries used the same type of calendar. Before then two main alternative calendars were in use (in different countries in Europe) - the Julian and Gregorian - giving different dates for the same day. The Julian had been in use since roman times (it was invented by Julius Caesar) but had gradually slipped out of synchronism with the seasons. Its use was based on the assumption that the year was exactly 365.25 days long so an extra day was inserted every fourth year (leap years). But the year is very slightly shorter than 365.25 days so that, in the long run, too many extra days were added and so an error slowly accumulated. Pope Gregory (XIII) had instituted calendar reform which reduced the errors. His new calendar did two things: firstly it defined a new rule for inserting leap years so that errors would not accumulate and secondly it removed the accumulated error. The accumulated error was removed by deleting some days from the civil calendar when the use of the new 'Gregorian' calendar was instigated. Catholic countries adopted the new system immediately with protestant ones following later; (some countries such as Russia did not adopt the Gregorian calendar until the early twentieth century). The Gregorian calendar is now in almost universal use. More information about leap years can be found at U.S. Naval Observatory's site.
