Is there any formula to compute exact flight duration with different time zone?

Question

When flight travels from one country to another country (with different time zone) , how do we calculate exact flight duration ?. is there a defined formula ?

Answer 1

I don't know about a formula. But take the duration of the flight, then count the number of time zones in between your departure location and destination.

For example, if I was to leave from Singapore to London at 8am local time in Sg and the flight was 12 hours, I would arrive 6am local time in Singapore. That would mean I have to minus 8 hours to know the local time in London as London is 8 times zones behind Singapore..

Basically, take the local time of departure + duration of flight then + if the destination is on the right side of the country time zone and - if it is on the left side.

I hope this helps. ;)
