My question is: Approximately, what is the time for Duha prayer according to Mecca time?

The time for Duha prayer begins when the sun has risen and ascended by the height of a spear (approximately 15 minutes after sunrise), and it extends until shortly before the sun's meridian (about 10 minutes before Dhuhr). The Duha time varies by country and can be ascertained through accredited prayer time websites.
