CALENDA'RIUM (ἡμερολόγιον). An almanack or calendar; which, like our own, contained the astronomical, agricultural, and religious notices of each month in the year; the name of the month, the number of days it contained, and the length of the day and night; the sign of the zodiac through which the sun passes; the various agricultural operations to be performed in the month; the divinity under whose guardianship the month was placed; and the various religious festivals which fell in it. The illustration (Calendarium/1.1) represents an original of marble, found at Pompeii, with the inscription for the month of January, printed at length, as a specimen of the whole, by its side.

2. A ledger in which bankers and money lenders kept their accounts with their customers; so termed because the interest became due on the calendae, or first day of the month. Seneca. Benef. vii. 10. Id. Ep. 87.
