FIELD: physics.
SUBSTANCE: clock with a menstrual calendar comprises a housing, a clock face, a clock mechanism and a means of indicating a menstrual cycle interfaced with the clock mechanism and configured to indicate the day of the menstrual cycle; the means of indicating the menstrual cycle is configured to set up and indicate the duration of a menstrual cycle and the day of the menstrual cycle and has a means of indicating the duration of the menstrual, a means of indicating the day of the menstrual cycle, configured to automatically switch from the last day of the menstrual cycle to the first day of the menstrual cycle, a mechanism for setting up and/or correcting the duration of the menstrual cycle, a device for setting the duration of the menstrual cycle, a mechanism for setting up and/or correcting the current day of the menstrual cycle, a drive for the means of indicating the day of the menstrual cycle. In the clock mechanism with a menstrual calendar, the menstrual calendar is in the form of a means of indicating a menstrual cycle, which is configured to indicate the duration of a menstrual cycle and indicate the day of the menstrual cycle.
EFFECT: simple design, high reliability and accuracy of indicating menstrual days with different personal duration, enabling automatic switching of the day of the menstrual cycle from the last day of the cycle to the first day of the cycle in a clock with a menstrual calendar.
