When Do the Clocks Change?
Clocks across Ireland will spring forward by one hour at 1:00 am on Sunday, 29 March 2026, as the country transitions from Greenwich Mean Time to Irish Summer Time. The adjustment means that 1:00 am will become 2:00 am, giving everyone one less hour of sleep but introducing longer, brighter evenings that mark the arrival of the summer season.
The clock change is a biannual event that affects Ireland and the broader European time zone simultaneously. Most digital devices, including smartphones and computers, will adjust automatically, but manual timepieces, kitchen appliances, and car clocks will need to be updated by hand.
Impact on Daily Life
The immediate impact is the loss of one hour's sleep on Sunday morning, which sleep researchers note can take several days to fully adjust to. Monday morning following the spring clock change historically sees increased reports of tiredness-related incidents, and the Road Safety Authority advises motorists to be particularly careful during their Monday commute.
On the positive side, the change brings an extra hour of evening daylight that extends well into October. The shift is particularly welcomed in Ireland, where the longer evenings facilitate outdoor activities, community events, and the general sense of wellbeing that accompanies brighter weather conditions.
The Debate About Abolishing Clock Changes
Periodic debate continues about whether Ireland should follow through on the European Parliament's 2019 decision to abolish seasonal clock changes. Proponents of permanent summer time argue that the health and wellbeing benefits of longer evenings outweigh the tradition of changing clocks. However, permanent summer time would mean darker winter mornings, raising safety concerns for schoolchildren and commuters during November, December, and January.
