Best time to meet between HST and BST

There is no overlap between 9 AM and 6 PM in both places.

If both sides can be flexible (7 AM – 10 PM):

  • 7:00 AM – 12:00 PM HST = 5:00 PM – 10:00 PM BST
  • 9:00 PM – 10:00 PM HST = 7:00 AM – 8:00 AM BST

The time difference changes during the year because of daylight saving time, so these windows shift by an hour at other times.
