Ireland has moved on to winter time this weekend, allowing for an extra hour of sleep on Sunday morning.
The change came into effect at 2am on Sunday when clocks should have been put back one hour.
Daylight saving time was introduced in Europe as a seasonal measure so that darkness falls later in the day.
Under the current system, the clocks are put forward one hour on the last Sunday of March and back again on the last Sunday in October.
In 2019, the European parliament voted to scrap the twice-a-year custom . The last change was supposed to be spring of this year but the reform has since been delayed.
Ahead of the time change, An Garda Síochána said there was international evidence to show there was an increase in burglaries in the order of 20 per cent in the winter months, when daylight hours are at the lowest level.
In winter, burglary most often occurred between 4pm and 9pm, gardaí said, urging people to be vigilant. Thursday, Friday and Saturday were the most likely days for burglaries to occur in winter, the force added.
Operation Thor, launched by the Garda, is designed to tackle the anticipated increase in burglaries by undertaking “targeted enforcement and preventative activity”.
Gardaí said they would have “visible focused patrols at specific times of day, targeting burglary hot spots, intelligence gathering on known offenders, and high-visibility checkpoints to prevent ease of movement”.
