Grahan (eclipse)
A solar or lunar eclipse, with a period of Sutak before it when many observances are paused.
How this site calculates it
Eclipses come from astronomy-engine's eclipse searches: lunar eclipses with an umbral phase (penumbral ones are left out), solar eclipses as seen from the place. Sutak starts 12 hours before a solar and 9 hours before a lunar eclipse, where it is visible.
