Example. If the taxpayer elects a taxable year ending always on the last Saturday in November, then for the year 2001, the taxable year would end on November 24, 2001. On the other hand, if the taxpayer had elected a taxable year ending always on the Saturday nearest to the end of November, then for the year 2001, the taxable year would end on December 1, 2001.
