摘要： PURPOSE: To provide a calendar of watch to which a correction function is added with a simple mechanism so as to supply automatic stepping as much as possible by considering that a difference slightly longer than 30 days of an odd-numbered month, 29 days of an even-numbered month and 354 days of a year intrinsic to a Moslem calendar by a leap year. CONSTITUTION: The first mechanism of this calendar dries a date indicator in which a numeral 1-30 is written, by one step independently of the rotation part of an analog watch movement at the end of every day. The second mechanism advances the date indicator from 29th to the first of the next month at the end of the even-numbered month in cooperation with the first mechanism. The third mechanism displays 30 before the date indicator is advanced to the display of the 1st in the final month of the leap year by suppressing the action of the second mechanism at the end of the leap year. The calendar is a perpetual calendar and the calendar is updated by the date indicator and a month correction part.
