1. Yesterday was his 100th day.
2. one hundredth day
3. a hundredth day

(How can we read '100th day'?)

Do you mean his 100th birthday? (Meaning he's 100 years old?)

Let me know.

and you can't say #3
======================
Thank you. Not 100 years old, but 100 days passed

I think rfvv is referring to the small celebration when an infant is 100 days old.

http://www.asianinfo.org/asianinfo/korea/cel/birthday_celebrations.htm

You could say, "This is his hundredth day on the job."

You could say, "This is the one hundredth day since the mine caved in."

But "a hundredth day" wouldn't be used.

Ah, I see.

So rfvv, how could you rephrase those sentences to reflect the 100th day celebration?

I think he's using "100th day" as we would say "birthday." Yesterday was his birthday.

To read "100th day," you can say either "his 100th day" or "one hundredth day." The phrase "a hundredth day" is not used in this context.

If someone says "Yesterday was his 100th day," it means that 100 days have passed since a certain event or starting point.

In this case, the person is clarifying that it is not the person's 100th birthday, but rather 100 days have passed since a specific event or milestone.
