He travelled during Ramadaan to a country where the people started Ramadaan on a different day
Question

                If I started fasting in my country then travelled to another country where they started fasting one day after us. Shall I continue with the Muslims there and fast the 31st day?.
Praise be to Allah.
    What matters when a person started fasting in one country and 
    finished fasting in a country to which he travelled, is that if the total 
    number of days that he fasted was twenty-eight, then he must make up one 
    day, because the lunar month cannot be less than 29 days. If he has already 
    fasted thirty days but the people in the country to which he has travelled 
    still have one more day to fast, for example, then he must fast with them so 
    that he may break the fast with them on the day of Eid, and offer the Eid 
    prayer with them.
