At what time of the year do the days become shorter?

Answer 1

The shortest day of the year is the Winter Solstice; in the northern hemisphere, that's generally December 21. On December 22, the day is longer by a matter of a few seconds, and on December 23, the day is longer by a couple of seconds more. We don't really start to notice the day length changing until mid January.

The length of day follows a sinusoidal pattern, and the day length is increasing fastest around the time of the equinoxes.

The US Naval Observatory has a calculator that can give you the times of sunrise and sunset for an entire year for your location.

Answer 2

The days start becoming shorter after the summer solstice, which occurs around June 21st in the Northern Hemisphere. This marks the beginning of the gradual decrease in daylight hours until the winter solstice around December 21st.

Answer 3

That depends on the latitude and on the date. Near the equator, the day length doesn't change appreciably from day to day. In the mid-latitudes, in the first few days after the solstice, the length of day changes by only a few seconds to a minute or so. Near the equinoxes, the day length may be changing by ten minutes or more each day.

The length of day follows a sine-wave shape, with peaks and troughs at the solstices and nodes at the equinoxes.

Answer 4

No... well, it's essentially constant for the same date from year to year, but the number of minutes of sunlight gained or lost each day varies in a sinusoidal curve throughout the year. It's also different for every latitude, so there's almost no variation in day length at the equator, with great changes at high latitudes.

Answer 5

From the Summer Solstice itself to the next day, or the day after, the differences are minuscule. But as summer progresses, the days get shorter faster and faster until the equinox, when the day length is changing fastest, and then it slows until the winter solstice. The length of the day in the temperate regions follows a roughly sine-wave shaped curve, changing fastest at the equinoxes and slowest at the solstices.

The difference in day length is dependent on latitude.

Answer 6

Today was the winter solstice in the northern hemisphere, the shortest day of the year. From now on until June 21, the days will be a little longer each day.

The day-to-day difference depends on your latitude and the date. In the middle latitudes and for the next week or so, each day will be a few seconds longer. After that, the days get longer faster each day until the equinox on March 21, at which time the daily increase will slow down. Approaching June 21, each day will be only a few seconds longer.

Near the equator, there will be very little difference from day to day throughout the year.

Answer 7

The answer is different for each place on Earth, and for each day of the part

of the year when that place is gaining.

Don't forget that for roughly half of the year, a place is losing minutes of daylight

each day.

Also don't forget that at the north and south pole, the sun is up for six months

and then down for the other six months.

Answer 8

The length of the day, and the change in the length of the day, varies in a year-long sinusoidal wave with the peak on June 21 (plus or minus one day because of the cycle of leap years) and a trough of December 21. Around those dates, the change in the length of the day is quite tiny.

The rate of change increases to the equinox, and then decreases until the next solstice.

Answer 9

Actually, the days start growing shorter from the summer solstice on, right through the summer and fall. That's because the Earth's axis of rotation is tilted about 23.5 degrees as compared to the plane of the Earth's orbit around the Sun.

Answer 10

After the summer solstice, days get shorter; after the winter solstice, the days get longer.

As to the "Why?" - well, you might consider this as one definition of the summer solstice: the longest day of the year.
