Though the Thomas almanacs through 1795 were ascribed by Evans to Ezra Gleason, most can be identified with varying degrees of certainty to other identifiable calculators. The present one, like those for 1786-1788, was calculated by Samuel Stearns. A letter from Stearns to Thomas, dated March 3, 1788, in the manuscript collections of the American Antiquarian Society, speaks of preparing copy for Thomas's 1789 almanac

In comparison between this almanac and Stearns' The universal calendar and the North-American almanack for 1789 (Boston), the only identical calculations on the calendar pages are those in the ephemeris and those for the rising, setting, and phases of the moon, and the rising, setting, and southing of the 7 stars or Pleiades. This exemplifies that appearance of a slight differential in calculations often noted when the same author is know to have prepared almanacs for different publishers. Though both the above almanacs were allegedly calculated for the meridian of Boston, the title of Thomas's suggests that it was intended to be applicable over all of New England, which may explain the differential in this instance
