The Continental almanac, for the year of our Lord, 1780 ..
Series: Early American imprints -- no. 16500
Publisher: Printed and sold by Francis Bailey, in Market-Street, between Third and Fourth-Streets.
Published: 1779
Place of publication: Philadelphia
Language: eng
Number of pages: 32
Notes: Evans attributes this almanac to David Rittenhouse, and is confirmed through comparison with the Maryland, Virginia and Pennsylvania almanack and ephemeris for 1780 (Baltimore), calculated by Rittenhouse. All calculations for the sun and moon, and those in the monthly ephemeris, are duplicated throughout. Some of the astronomical notes on the calendar pages have been omitted in the present almanac, and a few others added; the rest are identical, except that some of their calculations have been adjusted. The calculations on the eclipse page are an adjusted version.

The copy of the Maryland, Virginia and Pennsylvania almanack examined is that in the Darlington Library of the University of Pittsburgh. The supposed copy in the Maryland Historical Society, lacking a title page, appears to be in fact a copy of the Continental almanac. Cf. Wheeler, J. The Maryland Press, 1938, p. 98.
