An apostrophe used after the letter S at the end of the word generally means it is a plural possessive, such as "cats' meow" which is basically referring the meow to all of the cats (plural).
Sometimes, however, some words will end in an S without being a plural, such as names, but the apostrophe still indicates that it is possessive. For example "James' notebook" which is saying that the notebook belongs to a singular James.
The word there's is a contraction for there is. The apostrophe substitutes for the i in is.
The word "its" does not require an apostrophe when indicating possession, as in "The dog chased its tail." However, "it's" with an apostrophe is a contraction for "it is" or "it has," as in "It's going to rain today." To determine whether to use the apostrophe, consider whether you mean possession (no apostrophe) or a contraction (with apostrophe).
"Theres" isn't actually a word. "There's" is a word, and is a contraction of "There is". "Theres" must have an apostrophe to mean anything at all in the English language.
It means there is already an "s" at the end of the word
NO, if you typed "viruses'" (viruses with an apostrophe) it would mean "The viruses' (more than one virus's) something.
The word there's is a contraction for there is. The apostrophe substitutes for the i in is.
If you mean as an abbreviation of 'old', then the apostrophe would be at the end of the word (ol'), because the apostrophe shows that the 'd' at the end of the word has been omitted.

No, the word "holidays" does not have an apostrophe.
there is no apostrophe
It is not a word. It is two words: "it will". The "i" in "it" is not pronounced, and that is why there is an apostrophe there. You will quite frequently see the letter "t" with an apostrophe in front in Shakespeare, and it always means "it".
It means a word that is accompanied by "is" in a shortened form. Ex. He's in the kitchen.
