You should always be prepared for the time of need.

I woke up at the witching hour.

During rush hour, the trains are very crowded.

Following the customs of the time, they celebrated the festival.

I wake up at seven o'clock every day.

The beauty of the four seasons symbolizes the charm of nature in Japan.

I go to bed every day at ten o'clock.

When it becomes summertime, the days get longer.

I wake up at six o'clock every day.

Let's meet at the station at five o'clock.
