The gap between Virginia (Eastern Time) and the UK (Greenwich Mean Time / British Summer Time) shifts three times a year due to mismatched DST transitions:
| Period | Virginia | UK | Difference |
|---|---|---|---|
| Early Nov – Mid Mar (Standard both) | EST (UTC-5) | GMT (UTC+0) | 5 hours (UK ahead) |
| Mid Mar – Late Mar (US DST, UK standard) | EDT (UTC-4) | GMT (UTC+0) | 4 hours |
| Late Mar – Late Oct (DST both) | EDT (UTC-4) | BST (UTC+1) | 3 hours |
| Late Oct – Early Nov (UK standard, US DST) | EDT (UTC-4) | GMT (UTC+0) | 4 hours |
Key Dates: US springs forward 2nd Sunday March, falls back 1st Sunday November. UK springs forward last Sunday March, falls back last Sunday October.
Example: When it's 12:00 noon in Richmond, VA, it's 5:00 PM in London (Jan), 4:00 PM (Apr), or 3:00 PM (Jul).
