The two days, side by side
Each row is one city's day in its own clock, from London's midnight. The marked band is the working hour both of them are inside.

Through the year: what daylight saving does
The difference is not one number. It changes 2 times in the next twelve months, because the two sides switch their clocks on different dates:

How this page is calculated
Offsets and daylight-saving rules come from the IANA time zone database through the standard Intl API — the same source the board uses, so nothing here is a hand-written offset table. Working hours are 09:00–18:00 local on both sides unless you change them on the board. City names and coordinates: GeoNames (CC BY 4.0).
