Peacock and the issue year ၁၂၂၇ (CS 1227 or 1866 AD).

Peafowl is a species of birds that include two Asiatic species (the blue or Indian peafowl originally of India and Sri Lanka and the green peafowl of Myanmar (Burma), Indochina, and Java) and one African species (the Congo peafowl native only to the Congo Basin), his extravagant eye-spotted tail covert feathers which he displays as part of a courtship ritual. The term peacock is properly reserved for the male; the female is known as a peahen, and the immature offspring are sometimes called peachicks.

Between 1835 and 1887 Burma is known to have been using the year numbering system called the Chula Sakarat or Chulasakarat (CS), a lunisolar calendar derived from the Burmese calendar. The Burmese calendar is a lunisolar calendar in which the months are based on lunar months and years are based on sidereal years. The calendar is largely based on an older version of the Hindu calendar, though unlike the Indian systems, it employs a version of the Metonic cycle. The calendar therefore has to reconcile the sidereal years of the Hindu calendar with the Metonic cycle's near tropical years by adding intercalary months and days at irregular intervals.
