Maharaja Jai Singh II of Jaipur who built the Jantar mantar containing 13 architectural astronomy instruments in it, from 1724 onwards, and is one of those five built by him, as Mughal emperor Muhammad Shah who gave those by the task of scrutinize the calendar and astronomical tables. There is plaque fixed on one of the structures in the Jantar Mantar observatory in New Delhi that was fixed there in 1910 mistakenly dating the construction of the complex to the year 1710.

Some of these purposes in the Jantar mantar nowadays would be classified as astrology.

There are four different instruments within the observatory of the Jantar mantar in New Delhi are the Samrat Yantra, the Ram Yantra, the Jayaprakash, and the Mishra yantras.

Samrat Yantra: The Samrat Yantra, or Supreme Instrument, is a gigantic triangle that is basically an equal hour sundial in the Jantar mantar. It is 70 feet high and 114 feet long at the base, and 10 feet thick. It has a 128-foot-long (39 m) hypotenuse that is correspondent to the Earth's axis and points toward the North Pole. On the other side of the triangle there is a quadrant with graduations indicating hours, minutes, and seconds. At the time of the Samrat Yantra's construction, sundials already prevailed, but the Samrat Yantra turned the basic sundial into a precision tool for measuring rejection and other related coordinates of various heavenly bodies.

Jayaprakash Yantra: The Jayaprakash in the Jantar mantar subsists of hollowed out hemispheres with markings on their concave surfaces. Crosswires were expanded between points on their rim. From inside the Ram, an observer could affiliate the position of a star with various markings or a window's edge.

Mishra Yantra: The Mishra yantras of the Jantar mantar were proficient to indicate when it was noon in various cities all over the world and was the only architecture in the observatory not invented by Jai Singh II.
