Read a phrase as a year, the old way of hiding a date inside words.
The phrase's total is read as a year in the Islamic calendar, with the matching Western year beside it.
Short phrases work best — a name, a title, a single line of verse. Long sentences produce totals far outside any plausible year and tell you nothing. If you are trying to hide a date inside a phrase rather than read one out, adjust a word at a time and watch the total move.
