What does chronogram mean?
A chronogram is a phrase or inscription in which certain letters, usually those functioning as Roman numerals, combine to express a date. The device flourished in Europe from the sixteenth to the eighteenth centuries and was most often executed in Latin, since the numerals M, D, C, L, X, V and I appear naturally as capital letters within words. A builder might carve a pious motto over a doorway whose enlarged or highlighted letters silently record the year of construction, allowing the date to be embedded decoratively rather than stated plainly. Deciphering a chronogram involves picking out the numeral-bearing letters and reading them in order. Today the word survives chiefly in the study of inscriptions, architectural history, and wordplay, and it carries a scholarly, slightly antiquarian flavour. Related forms include the adjective 'chronogrammatic' and the noun 'chronogrammatist' for a composer of such verses.

Etymology of chronogram
The word derives from Greek khronos ('time') + gramma ('letter, written mark'), via the post-classical Latin chronogramma. It entered English usage around the early seventeenth century, when the fashion for date-hiding inscriptions was at its height. It shares its roots with words such as chronology, chronic and synchronise (all from khronos), and with diagram and epigram (from gramma).

How chronogram is actually used
A learned, somewhat rare word belonging to the vocabulary of epigraphy, heraldry, and classical scholarship. Chronograms flourished especially in the 16th–18th centuries and are most often found in Latin, where vowels such as M, D, C, L, X, V and I double as Roman numerals.

A chronograph is an instrument for recording time (such as a stopwatch), while a chronogram is an inscription concealing a date.
An anagram rearranges the letters of a word or phrase into another; a chronogram selects specific letters (usually Roman numerals) within a text to express a date.
