Do I need to change my phone and computer manually?

No. Any device that syncs its time over the internet updates itself. Car clocks, ovens, microwaves and older wall clocks usually need doing by hand.

2027 time change dates for Pennsylvania

Clocks go forward: Sunday, March 14, 2027

At 2:00 AM the clocks jump straight to 3:00 AM in Pennsylvania. That hour never happens, and everyone loses an hour of sleep.

Clocks go back: Sunday, November 7, 2027

At 2:00 AM the clocks return to 1:00 AM, so that hour is lived through twice and the night is an hour longer.

Pennsylvania keeps EST in winter and shifts one hour forward for the summer.

Health Considerations for Pennsylvania Residents

The spring transition is the one that hurts. A study in Open Heart found the risk of heart attack rose by about 24% on the Monday after clocks went forward, before falling back to normal within the week. Research published in Current Biology found a 6% rise in fatal traffic accidents in the week following the spring change, with the effect strongest in the morning and in the western parts of time zones.

The autumn change, when most people gain an hour, shows no comparable spike. Researchers attribute the difference to sleep loss rather than to the clock change itself.

Health Tip: Shift your bedtime 15 minutes earlier each night for the four nights before the spring change, so the hour is absorbed gradually rather than lost all at once.

Agricultural Considerations

The story that DST was introduced for farmers has it exactly backwards. Farmers in Pennsylvania and elsewhere were among its most persistent opponents, and the American farm lobby successfully campaigned to have national DST repealed after the First World War.

The reason is straightforward: farm work follows the sun, not the clock. Moving the clock forward just means doing the same work an hour earlier by the clock, while deliveries, markets and hired labour all shift with it. Dairy farmers make the point most often, since cows keep to their own schedule and take several days to adjust to a changed milking time.

Background

The European Parliament voted in 2019 to end mandatory clock changes, but member states never agreed on which time to keep, so the change has stalled indefinitely.
Germany and Austria-Hungary were the first countries to adopt DST nationally, in April 1916, as a wartime fuel-saving measure.
Arizona and Hawaii are the only US states that skip DST statewide, along with the territories of Puerto Rico, Guam, American Samoa and the US Virgin Islands.

Tips for Pennsylvania

💡

Use the phrase 'Spring forward, fall back' to remember which direction to change your clocks.

💡

Set your clocks before going to bed to avoid confusion in the morning.

💡

Remember that not all countries change on the same date - check international meeting times carefully.

💡

Be extra cautious driving the Monday after the spring time change - accident rates increase.

Frequently asked questions

When do the clocks change in Pennsylvania in 2027?

Clocks go forward on Sunday, March 14, 2027 and back on Sunday, November 7, 2027.

"Spring forward, fall back" is the usual mnemonic: forward one hour in spring, back one hour in autumn.

Do I have to change anything myself?

Phones, computers and anything that syncs over the internet update on their own. Car clocks, ovens, microwaves and older wall clocks generally do not.

Is Daylight Saving Time being scrapped?

It has been proposed in many places and adopted in few. The European Parliament voted in 2019 to end mandatory clock changes and the change has stalled; in the United States the Sunshine Protection Act has repeatedly passed the Senate without becoming law. Most of the world that changes its clocks is still changing them.
