Astrological Calendars – 6 – Batak Calendar

May 17, 2017 1 min read

The Batak Calendar system has 12 months and follows the phases of the moon and the sighting of the constellations.

Some basic facts

  • the month is divided into 3 groups of 10 days
  • The new year begins when the Orion constellation disappears in the Western sky and Scorpio appears in the East.

The purpose of the calendar, seen in Pustaha and bone inscriptions is to determine auspicious and inauspicious days for conducting life events rather than for calculating time.

Even though the Batak script existed, the main medium was oral literature and so the knowledge transmission is vulnerable to corruption and endangered.


Pustahas or books written on the bast of the Alim tree after preparing it with rice paste. The books cover – among other subjects – the art of fortune telling based on the Batak calendars.

The same system is also used to inscribe fortune telling texts on bone.
