Is there a difference in sunset times in London and in the west of Ireland?

Answer 1

Of course.

The time of sunset is when the sun goes below the horizon.

As the west of Ireland is further west than London, the sun sets later there, even though they share the same time zone.

There are 360 integral lines of longitude dividing the globe, with 0 running through London.

The sun covers these in 24 hours, so each one of these represent a time difference of 4 minutes from its neighbours.

Galway, for example, is at longitude 9º west, so the sunset there will be approximately 36 minutes later than in London.

Today - 16th February 2011

Sunset in London will be at 5:16pm Wednesday (GMT)

Sunset in Galway will be at 5:48pm Wednesday (GMT)

Answer 2

Yes, there can be differences in sunset times between London and the west of Ireland due to their geographical locations. The west of Ireland typically experiences slightly later sunsets compared to London because it is further west, closer to the Greenwich Meridian. This means the west of Ireland may have a slightly longer period of daylight in the evenings.
