Story: Western European Summer Time (WEST) is a summer daylight saving time scheme, 1 hour ahead of Coordinated Universal Time. It is used in: 

Western European Summer Time is known in the countries concerned as: 

The scheme runs from the last Sunday in March to the last Sunday in October each year. At both the start and end of the schemes, clock changes take place at 01:00 UTC. During the winter, Greenwich Mean Time (UTC+0) is used. 

The start and end dates of the scheme are asymmetrical in terms of daylight hours: the vernal time of year with a similar amount of daylight to late October is mid-February, well before the start of summer time. The asymmetry reflects temperature more than the length of daylight. 

Ireland observes Standard Time during the summer months and changes to UTC+0 in winter. As Ireland's winter time period begins on the last Sunday in October and finishes on the last Sunday in March, the result is the same as if it observed summer time. 

The following countries and territories use Western European Summer Time during the summer, between 1:00 UTC on the last Sunday of March and 1:00 UTC on the last Sunday of October. 

In Ireland, since the Standard Time (Amendment) Act, 1971, Ireland has used UTC+1 in summer (officially "standard time", , though usually called "summer time") and UTC+0 in winter (officially "winter time").
