Answer
Ivan V was born on August 27 (Old Style) in 1666, which corresponds to September 6 in the Gregorian calendar currently in use. The difference in dates is due to the calendar reform introduced in 1582 by Pope Gregory XIII, which adjusted the Julian calendar to align more precisely with the Earth's orbit around the Sun.
