All the almanacs published in Pennsylvania for 1781 except the American almanac contain the same calculations and have most of the same astronomical notes on the calendar pages, and are clearly the work of the same author. In some, the calculations for the sun are adjusted slightly for spring and autumn. The only one of these almanacs naming a real person as its author is Der Gantz neue verbesserte nord-americanische Calender (Lancaster), by David Rittenhouse. It differs from the others only in having fewer notes and columns of calculations, as is usual with German-American almanacs.
