This weekend will be one hour shorter, thanks to the annual change to daylight saving time in California on Sunday morning.
The “spring forward” ritual begins at 2 a.m. Sunday, meaning it’s time to turn clocks ahead by one hour. Luckily many timekeeping devices do this automatically now.
The change means California will shift to the same time as Arizona, which does not switch to daylight saving time along with the rest of the Mountain Time Zone. Hawaii also stays on its standard time, meaning the islands will be three hours earlier than San Diego for the next half year, instead of two hours.
Daylight saving time was introduced in the United States during World War I to save energy during the extra hour of daylight. In later years the purpose became keeping daylight for after-work leisure activities.
As usual, firefighters urge people to use the time change as a reminder to check smoke alarms and replace the batteries if necessary.
The San Diego County Water Authority reminded homeowners to adjust irrigation controllers so they match the season.
