Clocks go forward at the beginning of official summer time. The daylight saving will not mean that the weather gets any better.
The clocks go forward everywhere in Ireland apart from the Air Traffic Control Centre at Dublin Airport and other airports around the country. Until next October, when the clocks go back again, they will be one hour behind the rest of us but on time with all other western airlines. Air traffic works with Greenwich Mean Time (GMT).
For farmers, official summer time means more daylight for their most important season.
More light for ploughing and planting. Longer hours for cows out in grass with a resulting increase in milk production.
The ESB is also impacted by the time change with more electricity being used in the mornings with peak time now around 9.00 am. There will be a bigger use of lighting in the darker mornings which is balanced off by a fall in demand in the brighter evenings.
Street lights too will come on and off at different times as they are now activated by levels of light and darkness.
Until 15 April, the pubs too will remain on winter time closing at 11.00 pm.
