If its January 7 1000 PM in New York city what date and time is it London?

To calculate the date and time in London, you need to account for the time difference between New York City and London. New York City is in the Eastern Time Zone (UTC-5), while London is in the Greenwich Mean Time (UTC+0) zone. So, there is a 5-hour difference between them.

If it's January 7, 10:00 PM in New York City, subtract 5 hours to find the equivalent time in London.

10:00 PM (New York time) - 5 hours = 5:00 PM (London time)

Therefore, January 7, 5:00 PM would be the date and time in London.
