====== Date indication ====== {{wst>image_cl|Bell & Ross|Vintage 126 XL Edition Limitada|Bell & Ross Vintage 126 XL Edition Limitada with\\ **digital date indication**\\ below the "12"}} A **date** complication shows the date (day of month). It can also be part of a comprehensive [[calendar]] complication. A simple date display is extremely simple, advancing a disc or hand once every two revolutions of the [[hour hand]]. Many watches feature both [[day]] and date, and some have more complicated [[calendar]] functions, including month and even year. The date display typically uses a simple wheel mechanism with each date from 1 to 31 written on a disc and viewed through an [[aperture]] in the [[dial]]. In a simple date mechanism, the wearer must manually advance the date on months with 28, 29, or 30 days. A mechanism that can keep track of these monthly differences is called an [[annual calendar]] or [[perpetual calendar]]. The numerals on the date wheel can be of a single color, often coordinated with the dial, or multiple colors (e.g. the so-called [[Rolex]] [[roulette date]]). The date can also be displayed by [[pointer]], with a hand indicating the current date using printing on the dial. Date by pointer is often central to the dial using a decorative hand, often with a sun or moon at the tip. ===== See also ===== * [[Day]] * [[Rising date]] * [[Roulette date]] {{tag>Terms}}
