# When can I ring Delhi from London?

Delhi keeps the same clock all year, so every change in the gap comes from London. When the UK moves its clocks forward in March, Delhi feels an hour closer; in late October it moves an hour away again.

A call before work in London reaches Delhi around lunchtime. By the time you are home in the evening, it is late at night there, so the morning is usually the easier slot for both of you.

We assume you are up from 7:00 to 22:00 and that 9:00 to 21:00 is a fair time for them to take a call. Change the hours in the tool above if they keep others.
