British Summer Time and the European Union
The British Summer Time Act was created in 1972 which started the tradition of changing the clocks in late March (subject to the date of Easter) and late October. Twenty years later, the changing of the clocks in Britain was aligned with other European countries and from 2002 onwards, the EU stipulated that all member states should adjust their clocks on the last Sunday in March and October. Iceland is exempt from this directive, due to its northerly latitude and extreme variations in daylight and darkness throughout the year.
In March 2019 the European Parliament
backed a proposal to end the practice of changing the clocks in European Union states. Initially the plan was for EU nations to change their clocks for the last time in 2021, but the legislation has stalled in recent years. For the time being, EU nations continue to implement seasonal time changes.
Daylight saving time around the world
Currently, about 70 countries worldwide adopt some form of daylight saving, mainly in Europe and North America. For countries in the equatorial regions, there is little variation in the length of daylight across the year, with roughly 10-12 hours of daylight and 10-12 hours of darkness each day, so daylight saving offers no benefit.
