That week both places are on standard time. The table uses the same rules for every day of 2027. The finder above recalculates for the current week in your browser.

Stop doing the math every day
The Long Goodbye keeps your person’s local time and time of day on your home-screen widget and lock screen, so you can see whether it is morning coffee or midnight in London before you call. A “thinking of you” tap lights up their widget, and a countdown keeps the next visit in view.
What is the time difference between London and Miami?
London is 5 hours ahead of Miami for most of the year. Because the two places change their clocks on different dates, the gap is 4 hours from 14 March to 27 March and from 31 October to 6 November 2027.
What is the best time to call London from Miami?
In January, the easiest two hours on a weekday are noon – 2 pm Miami, which is 5 – 7 pm London: Miami lunchtime, London early evening, during Miami’s lunch break. At the weekend, Sat 1 – 4 pm Miami (Sat 6 – 9 pm London) gives you a longer call. Change the awake and work hours in the finder on this page to fit your own days.
How many waking hours do London and Miami share?
If both of you are awake from 7 am to 11 pm, you share 11 hours on a January weekday, and 1 hour of them fall outside 9-to-5 working hours in both places.
Does daylight saving time change the call times?
Yes. In 2027 Miami changes its clocks on 14 March and 7 November and London changes its clocks on 28 March and 31 October, so a call you keep at the same time in Miami moves by an hour in London on those dates. Check the table on this page and agree the new time out loud after each change.
