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 Delhi before you call. A “thinking of you” tap lights up their widget, and a countdown keeps the next visit in view.

At the weekend, Sat 7:30 – 10:30 am Chicago (Sat 7 – 10 pm Delhi) 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 Delhi and Chicago share?
If both of you are awake from 7 am to 11 pm, you share 8 hours on a January weekday, and 4 hours of them fall outside 9-to-5 working hours in both places.
Does daylight saving time change the call times?
Yes. In 2027 Chicago changes its clocks on 14 March and 7 November and Delhi does not change its clocks, so a call you keep at the same time in Chicago moves by an hour in Delhi on those dates. Check the table on this page and agree the new time out loud after each change.
