Yes, there are correct & incorrect ways to write out the dates! As a wedding stationery designer, nothing hurts more than seeing improper date format on wedding invitations. Below is my short, sweet, quick & cute guide for making sure the date format is correct on your wedding invitations.
Keep it short & sweet:
04.08.2023
4.8.23
Get a 'lil fancy:
April 8, 2023
***Do NOT include "TH", "ST" or "RD" in this format!
Even though you would say "8th" in person, it is NOT grammatically
correct to include "th" in text.
Get really fancy:
Saturday, the eighth of April, two thousand twenty-three
***Yes. A hyphen is correct.
