Day of Arafaah in different time zones
Question

                What will be the day of Arafat for countries that are in different time 
zones?
Praise be to Allah.
The day of ‘Arafaah and the fasting that goes with it should be observed in each 
country according to the local times of fajr and maghrib. Fasting on this day expiates 
the sins of two years, as the Prophet 
 (Peace & Blessings of Allaah be upon Him) said: "Fasting the day of ‘Arafaah, I hope, will 
expiate the sins of the year before it and the year to come, and fasting the day of 
‘Aashooraa’ (the tenth day of Muharram), I hope, will expiate the sins of the year 
before it." (Reported by Muslim, 1976).
And Allaah knows best.
