Yangtoupa (Yangdouba) and Yangtoupi (Yangdoubi) are the god and the goddess of time in Meitei mythology, folklore and religion (Sanamahism) of Ancient Manipur (Antique Kangleipak). The earliest known record of the existence of the cult of the two time controlling deities dates back to the 2nd century AD during the reign of King Khuyoi Tompok (aka "Khuiyoi Tompok"). The wooden statues of the two deities are the first known sculptures ever created.
The wooden idols of the two deities are the supporting devices to the ancient Meitei time measuring device. The two deities mounted on the frame, being separated by seven "Kangkhils" (seeds). Yangtoupa (Yangdouba), the god, is allowed to move towards Yangtoupi (Yangdoubi), the goddess, after each dip of the bowl. When the two deities meet each other, one day of the month is recorded according to the set mechanism.
The two deities are offered foods and worshipped by the Tanyeishang Loishang (lit. "Time Keeping Office") on the day of Cheiraoba (Meitei new year). In honor of the two deities, the Loishang (lit. "office") celebrated the Cheiraoba. This is an important part of the Meitei tradition.
