The first thing you didn't know about daylight saving time.

It was all about bugs.

An entomologist named George Vernon Hudson was one of the first to seriously push this.

He was frustrated by how early the sunset during the summer months, which cut short his bug hunting.

He thought springing the clocks forward would allow more daylight for bug collecting.

The clocks could then be switched back in the winter, when it was too cold.

It wasn't until 1916 when daylight saving time was actually first practiced.

Germany, Austria and Hungary used it to conserve cold during wartime. 00:00:57.430 --> 00:01:5.600 Studies have shown that in current times, D S T saves enough energy to run about 100,000 households for one year. 00:01:5.610 --> 00:01:8.870 Theo Third thing you didn't know about daylight saving time. 00:01:8.890 --> 00:01:12.140 The time change happens at 2 a.m. For a reason.

By waiting until two in the morning to give or take an hour.

The idea is that most workers with early shifts will still be in bed, and most bars and restaurants will already be closed when losing that hour of sleep.

When we spring forward, be careful on your commute because there's a 17% average spike in car accidents.

The Monday after we move the clocks, speaking of commutes starting at 2 a.m. and track will shorten.

Stops were possible because trains can't magically jumped down the track to make up for the last hour.

So don't be late.
