According to Wikipedia, “Season’s Greetings” is a term that wishes people well over the holiday season regardless of their religious beliefs.
We tend to use the phrase more in writing than in speaking. It first appeared on winter season greeting cards along with “Merry Christmas,” “Compliments of the Season,” and “Christmas Greetings” in the late 19th century. “With the Season’s Greetings” or simply “The Season’s Greetings” was shortened to “Season’s Greetings” in the 1920s.
I love seeing the phrase. However, please remember “Seasons Greetings” – without the apostrophe – means greetings for many seasons. It is generic. And although you may like the person so well that you want to wish them good tidings for numerous seasons to come, let’s get a little more personal and take it one step at a time. Let’s wish them the best life can bring them throughout the upcoming holiday time.
