This is largely to taste. An apostrophe doesn't always mean it's possessive, as just demonstrated, but it is also used for plural abbreviations or for numbers (like 1960's).

A nitpick: don't use the apostrophe in the phrase "in the 1960s". It's not a possessive in that sentence.
See, e.g., https://www.thepunctuationguide.com/apostrophe.html
This is not a hard-and-fast rule. There's hardly agreement in style guides on this note. Don't be a jerk and nitpick style on the internet; it does not add to the conversation. https://english.stackexchange.com/questions/13631/is-an-apos...

A nitpick, in your comment, it should be “FAQs” not “FAQ’s”.
That's peanuts compared to the typos in "tommorow", also in the FAQ.
