The shift ignores the year: +19 days means 19 days later in the calendar. ISO weeks run Monday to Sunday. Moon-based: future dates are expected, and official announcements can differ by a day. Dates: India's dates, from the holidays package; regions of India sometimes mark the main day a day apart.
Diwali follows the Hindu lunisolar calendar: it falls on the new moon of Kartika, between mid-October and mid-November, so it swaps between October and November, and the shopping season before it with it.
When a holiday or the days around it change month, one month looks better and another worse against the year before, even if nothing about the business changed.
