The ABA Software DiskIssues 62, 67 and 68 presented programs that computed the date of Easter for any Gregorian year, corrected published carbon-14 dates for the effect of the decay of the earth's magnetic field, which is usually ignored, and computed some astronomical data such as the mean longitude of the sun, the number of days elapsed since the new moon, the first days of spring, summer, fall, and winter that years, and the day of the week, for any given day.
