Yes, there is an apostrophe in St. Patrick’s Day.
And also in Mother’s Day, Father’s Day, Lincoln’s Birthday and Valentine’s Day.
It’s also in New Year’s Day — uppercase as a proper noun (the holiday’s name) but lowercase if you’re wishing someone a happy year ahead.
Lincoln’s Birthday for the holiday, but “Lincoln’s birthday is on Feb. 12.”
Likewise, “season’s greetings” also has an apostrophe.
But no apostrophe in Veterans Day, Presidents Day or of course Martin Luther King Jr. Day.
No “S” in Groundhog Day.
No “S” in daylight saving time — and lowercase — but PDT, EST, etc.
Lunar New Year — preferred over Chinese New Year because it’s not just for China
Columbus Day, Indigenous People‘s Day — both acceptable, depending on locality
New Year‘s Day
New Year‘s Eve
Happy New Year!
Partially lowercase if used this way:
Have a happy new year.
We wish you a merry Christmas.
Sending season‘s greetings,
Always lowercase unless part of a proper noun:
summer, fall, winter, spring — but the Winter Olympics (proper noun)
summertime, summer solstice
Fourth of July, July Fourth, Independence Day — all three are acceptable and uppercase
