chronogram means A sentence or inscription whose letters, when interpreted according to a system (such as Roman numerals) in which letters correspond to numeric values, stand for a particular date (usually the date of inscription) when rearranged.
Why “chronogram” is a great word
A chronogram is a coded inscription in which certain letters, interpreted as Roman numerals, sum to a specific date, usually that of the inscription's creation. From the combining form chrono-, from Ancient Greek χρόνος (khrónos, "time") + -gram, from Ancient Greek γράμμα (grámma, "letter, writing"). Unlike an acrostic, which spells a name with initial letters, or a phylogenetic tree, which diagrams biological time, a chronogram is a numerical secret locked within a textual shell. It is the church bell whose dedication hides the year of its casting in its capital letters, the papal monument whose carved boast secretly memorializes its own erection, or the poet's line where the numerals secretly spell a birth year. The chronogram trusts that time can be hidden in plain sight, a quiet testimony that we have always measured our lives in letters, and letters in numbers.
