An equinox occurs twice a year when the day and night have approximately equal length. "Around 200 students from various city schools participated in the event," an official of the NGO, Science Popularisation Association of Communicators and Educators (SPACE), said.

"The autumn equinox is one of the best occasions to celebrate this wonderful phenomenon using the ancient instruments at Jantar Mantar," added the official.

According to SPACE, an international citizen science project — ‘Project Paridhi — Measure the Earth Again' was also flagged off on the occasion.

"The children performed experiments to measure the earth using a gnomon (a stick/sundial) to measure the shadows and in turn getting readings," said an official.
