The lunar shroud will begin at around 10.52pm on Monday night (August 7) and will proceed till 00.48am IST.
"The best shroud, that is the point at which the moon will be secured to the most extreme degree will be around 11.50pm. The extent of the overshadowing, which implies the portion of the lunar measurement, will be obscured at the best shroud minute at around 0.25 greatness.

A lunar shroud happens just at full moon. At the point when the sun, earth and moon arrive in an immaculate straight line and as the Sun's beams falls on the Earth and its (Earth's) shadow falls onto a fix of space and the moon enters that fix a lunar shroud is seen, he said.
The shadow is made out of two cone-molded parts, one settled inside the other. The external shadow or penumbra is a zone where Earth shadow is fractional and obstructs a few, however not the majority of the Sun's beams.
Conversely, the inward shadow or umbra is an area where Earth hinders all immediate daylight from achieving the Moon. It is just when a piece of the Moon goes through the umbra, an incomplete lunar shroud is seen.
