What happens when one swears off wine for the year and then the year turns out to have an extra month? What happens if the person swearing off the wine specified Adar in his vow - but didn't specify Adar I or Adar II, then what are the implications for the length of the vow? Also, what happens when the vow specifies Pesach? Given the presumption of wine on the first night if Pesach. Plus, Ezra's decree about garlic. Plus, other vows specifying meals, etc. Do we hold people to this kind of extreme language?!
