After receiving many nice comments and discussing some of the academic points above I have additional comments.
Connection to library cataloging -- Entering the year is an important part of the catalog record. The date helps keep editions straight. There are well established practices for entering Hebrew dates and making sure the correct civil date is indicated. For example from now until January 1, 2015, one must be careful about the Hebrew year of 5775. The the year may be entered as 2014/2015.
Every year publishers will issue books with the following year on the title page. For example the publisher puts "2015" on the title page and copyright date, but sells the book months before January 1. The rules tell the cataloger to record the date as written on the title page and usually a note will be added to remove confusion. Before I wrote the above piece I never thought about a difference in date on a British book when compared to the date in Europe. We would record the date from the title page. The first law of copyright, The Statue of Anne was effective in February 1709. However, the year was 1710 in Europe.
Noise making -- The sound of the shofar is loud and piercing sound. In the month before Rosh Hashana we blow the shofar every morning. On the morning of the 29th of Elul we do not blow the shofar with the reason given, "we want to confuse the Satan (evil spirits). If the shofar blower has difficulty blowing on the day of Rosh Hashana the folklore says that Satan is in the shofar preventing the sound form emerging. These ideas may be related to the noise making on new year for other cultures. The difference is the law of blowing and listening to the shofar. One is required to listen to 100 sound blasts. Someone calls out each sound so that the shofar blower can concentrate on the sound. Each blast must be perfect or it must be repeated until it is correct.
