I want to know the answer to the following question:
How many days are counted between Passover and Shavuot?
All the background I'm provided with is that "Similarly, when Jewish families and larger groups sing traditional Sabbath songs known as zemirot outside the context of formal religious services, they usually do so a cappella, and Bar and Bat Mitzvah celebrations on the Sabbath sometimes feature entertainment by a cappella ensembles.". Is that enough to answer the question?
