The first thing I do when trying out a new WordPress theme is get rid of the code that puts “th” and other such terminals after the number in a date.
Ex. January 1st, November 12th
Dates, like certain other written expressions, assume certain information on the part of the reader:
One writes January 1, but says “January first.”
One writes November 12, but says “November twelfth.”
The only time to use the “th, nd, rd” and “st” with numbers is with ordinal numbers.
Ordinal numbers are those used to indicate a progression.
Ex. first, second, third, fourth, fifth and so on. When written as numerals, they take the little terminals: 1st, 2nd, 3rd, 4th, 5th, 6th
Some other words that assume information on the part of the reader are:
Xmas – so spelled, but meant to be pronounced “Christmas.”
Mr. – pronounced “Mister.”
Mrs. – Now pronounced “Missus,” which is a reduction of earlier “Mistress.”
On the other hand, the only way to pronounce the politically correct Ms seems to be “Miz.”
By the way, if you want to get rid of the “th” after dates on your site, find the code
(‘l, F jS, Y’) and delete the S.
