一日二日 pronunciation I was trying to determine the pitch accent for the phrase when it means "for a day or two" and realised I might not even have the right reading. I thought it would be , but then I realised that the reading of is still even when it means "for two days". So should it be (with the normal pitch accent on each word)?

This word would be only read following the regular pattern. 2-10 days use Japanese reading (), but "1 day" is always Chinese, unless you refer to "the first day of the month" ( < "month" \+ "launch").

The accent is usually just like two separate words: {LHHH}{LHH}, but merged accents ({LHHHHHH}, {LHHHLLL}) are sometimes heard.

However, you can also say the same thing with numbers factored out: , then it will be exceptionally read . See this post for more about this formula.
