Weeks between dates calculation example

Problem: how many weeks are in the school year between September, 1st, 2021 and May, 31st, 2022?

Solution:

Calculate the number of days between September, 1st, 2021 and May, 31st, 2022. According to the How many days are there between two dates? calculator, the number of days is 272.
Divide this number by 7 and round down:
272/7 = 38.85, and it is 38 rounded down.
Calculate the integer remainder after division:
272 - (38*7) = 6

The answer: There are 38 weeks and 6 days in the 2021 school year. (Well, different countries have different start and end dates of a school year)

And here is how you should enter this problem into the calculator above: weeks between two dates calculation example

Visible planets (evening)

Jupiter is easy to spot, brighter than all the stars. It’s high in the south after sunset. It sets around midnight local time in mid-December and is gone before midnight at month’s end.
Mars rises in the east before sunset and is visible all night. It’s very red now and brighter than most stars, racing away from its recent December 8 opposition, when Earth flew between Mars and the sun.
Saturn is low in the southwestern sky after sunset – golden in color, shining steadily – best time for observing is right after darkness falls. It sets by around 9 p.m. local time in mid-December and around 8 p.m. at the end of the month.
Venus, the brightest planet and next planet inward from Earth in orbit around the sun, is climbing higher each night in the sunset twilight. By the end of December, it sets about 70 minutes after sunset.
Mercury is near Venus in the evening twilight and will reach greatest elongation on December 21, 2022. Visibility of this elusive planet improves throughout the month.

Visible planets (morning)

On December mornings, Mars is shining brightly in the west (opposite the sunrise horizon).

People often ask if our charts apply to them. Yes, if you’re in the Northern Hemisphere. Not as precisely, however, if you’re in the Southern Hemisphere. Our charts are mostly set for the northern half of Earth. To see a precise view from your location, try Stellarium Online.

Visible planets and night sky guide December, 2022

See all 5 bright planets in December

You can see all 5 bright planets after sunset this December. But you’ll need a clear horizon from the southwest to the east. Start looking about 30 minutes after sunset. Mercury and Venus are very low on the horizon but will rise higher later in the month. Once you catch Mercury and Venus, then scan the southern and eastern sky for Saturn, Jupiter and Mars. To see a precise view from your location, try Stellarium, the free web-based planetarium. Later, beginning around December 24 – Christmas Eve and Christmas Day – you can watch as the waxing crescent moon begins moving up past the line of planets. Read more about seeing all 5 bright planets. Chart via John Jardine Goss / EarthSky.

December evenings: Jupiter very bright in Pisces

Jupiter, the largest planet in our solar system, shines brightly in the early evening sky. In fact, it’s the brightest “star” in our southern night sky; you can’t miss it. Indeed, it’s probably the first star you’ll see as the sky starts to darken after sunset. Jupiter lies directly south of the eastern side of the Great Square, a group of 4 stars in the constellation Pegasus. Also, between the Great Square and the bright planet is a pretty but faint group of 6 stars known as the Circlet. They compose the western section of the constellation Pisces the Fishes. Chart via John Jardine Goss/ EarthSky.

December evenings: Planets Mercury and Venus are back!

After nearly a 2-month absence, Venus has returned! Venus, our brightest planet, glows very low in the sunset direction shortly after the sun sets. Additionally, Mercury is also back and joins Venus in our evening sky. Its path for December is indicated by the line and arrow in the chart above. Mercury will reach greatest elongation from the sun on December 21, 2022. By the way, this will be the 4th evening elongation for Mercury in 2022. How soon will you see Venus and Mercury? An EarthSky team member spotted them already using averted vision. They will be easier to spot starting about mid-month when they are visible about 30 to 40 minutes after sunset. The pair are about 5 degrees apart earlier in the month and are closest (within 1.5 degrees) on December 28. Later, after the close conjunction, Venus will climb higher in the evening sky, and Mercury will disappear around the end of the year. Then, Venus will go on to remain our brightest evening star through July 2023. Chart via John Jardine Goss/ EarthSky.

December evenings: Saturn in Capricornus

In the early evening, Saturn shines in the dim but pretty constellation Capricornus the Sea-goat, which lies low in the southwest after darkness falls. If you have a dark sky, you’ll notice that Capricornus has the shape of an arrowhead. However, Saturn is past its best viewing for the year, so you’ll want to catch it as soon as you can after dark. Saturn sets by about 9 p.m. local time mid-month and will be setting around 8 p.m. at month’s end. Chart via John Jardine Goss/ EarthSky.

Visible planets and night sky guide January 2023

January evenings: Venus and Saturn near each other

Brilliant Venus and golden Saturn pair up in the January 2023 evening sky. Shortly after sunset, bright Venus climbs higher in the west-southwest each evening, while the dimmer Saturn sinks lower. They are near each other on January 20-24, and are closest on the evening of January 22, 2023, when they are 0.4 degrees apart. Venus will reach its greatest elongation from the sun on June 4, 2023, and be visible in the evening sky through August. Saturn is best viewed in early January and poorly placed by month’s end. Saturn will be in conjunction with the sun on February 16, 2023, then emerging as a morning object in March. Chart via John Jardine Goss/ EarthSky.

Jupiter evenings: Jupiter in Pisces

Jupiter, the largest planet in our solar system, shines brightly in the January 2023 evening sky. It’s the brightest “star” high in our southwestern night sky; you can’t miss it. In fact, it’s probably the first point of light you’ll see as the sky starts to darken after sunset. Jupiter lies south of the eastern side of the Great Square, a group of 4 stars in the constellation Pegasus the Winged Horse. And between the Great Square and the bright planet is a pretty but faint group of 6 stars known as the Circlet. They comprise the western section of the constellation Pisces the Fishes. You’ll need a dark sky to see the faint stars of Pisces. Chart via John Jardine Goss/ EarthSky.

January evenings: Mars in Taurus

In the evenings throughout January 2023, bright red Mars is in the constellation of Taurus the Bull. It’s near the shimmering Pleiades star cluster. Also nearby, the bright red star Aldebaran can guide you to a “V” shape star cluster known as the Hyades. Mars is well placed for observing most of the night. By the way, on December 8, 2022, Mars reached its once-in-2-years opposition. So in January, Mars is the brightest it will be this year but will start the month at magnitude -1.2 dimming to magnitude -0.3 at month’s end. Chart via John Jardine Goss/ EarthSky.

January 2 and 3 evenings: Moon near Mars and Pleiades

The waxing gibbous moon sits high in the sky next to the glittering Pleiades star cluster on January 2, 2023. Then for the Northern Hemisphere, the moon is below Mars the following night of January 3. Southern Hemisphere? Look north and turn this chart upside down. The waxing gibbous moon is up at sunset and sets a few hours before dawn. The fiery red star near Mars is Aldebaran, the Eye of Taurus the Bull. Mars reached its once-in-2-years opposition on December 8, 2022. As Mars and Earth separate in their orbits, its brightness will continue to fade. Read more about the moon near Mars and Pleiades. Chart via John Jardine Goss/ EarthSky.

January 3-4: Quadrantid meteor shower

January 4 and 5 evenings: Moon near Mars and Orion

On the nights of January 4 and 5, 2023, the bright waxing gibbous moon moves above Orion the Hunter and slides eastward away from Mars. Below Mars is the fiery red star Aldebaran, the Eye of Taurus the Bull. While Mars currently rivals our brightest stars, it is at its brightest for this year. Mars was recently closest to Earth on November 30, 2022, and reached opposition on December 8, 2022. Read more about the moon near Orion. Chart via John Jardine Goss/ EarthSky.

The instant of full moon is 23:08 UTC on January 6 (5:08 p.m. CST on January 6)

January 6 and 7 evenings: Moon near Castor and Pollux

The full moon shines brightly by Gemini‘s twin stars, Castor and Pollux, all night on January 6, 2023, with the waning gibbous moon passing them on January 7. In the Southern Hemisphere, the waning gibbous moon pairs closest with Castor and Pollux on January 7. Although the twin stars don’t look alike, they are quite noticeable near each other in the sky, because they’re bright and close together. Castor is the slightly dimmer star of the pair. And Pollux is more golden in color. Also nearby is Procyon, the brightest star in Canis Minor the Lesser Dog. It’s sometimes called the Little Dog Star. Read more about the moon near Castor and Pollux. Chart via John Jardine Goss/ EarthSky.

January 10 morning: Moon near the Sickle of Leo

The morning of January 10, 2023, finds the waning gibbous moon glowing in the Sickle of Leo the Lion. If you aren’t an early riser, you can see the moon near Leo starting mid-evening – the night before – on January 9. You’ll notice the bright star Regulus as well. Regulus is the only 1st-magnitude star that sits almost right on the ecliptic, the path the sun follows through the sky. So Regulus is often near a bright planet and can even be occulted by the moon. Chart via John Jardine Goss/ EarthSky.

January 14 and 15 mornings: Moon near Spica

The morning of January 14, 2023, finds the waning gibbous moon near the star Spica in Virgo the Maiden. Then on January 15, the waning crescent moon glows in the southeast next to the star Spica. In fact, after midnight – on both days – you can see the moon near Spica. The last quarter moon occurs at 2:10 UTC on January 15 (or 8:10 p.m. CST on January 14). Chart via John Jardine Goss/ EarthSky.

The instant of last quarter moon is 2:10 UTC on January 15 (8:10 p.m. CST January 14)

January 17 and 18 mornings: Moon near the Crown of Scorpius

On the morning of January 17, 2023, the waning crescent moon floats above the Crown of Scorpius in the brightening morning twilight. On the following morning, January 18, an even thinner crescent moon lies immediately left of the fiery red star Antares, the brightest star in Scorpius the Scorpion. In the Southern Hemisphere, the moon is closest to the Crown of Scorpius on January 18. Also, the beautiful glow you see on the unlit portion of the moon is earthshine. Chart via John Jardine Goss/ EarthSky.

January 19 morning: Moon near Mercury

The very thin waning crescent moon hangs in the southeastern sky before sunrise on January 19, 2023. It sits to the right of Mercury in the morning twilight. (Above Mercury for those in the Southern Hemisphere.) Mercury will reach greatest elongation on January 30, 2023. Look for the lovely glow of earthshine on the unlit portion of the moon. Higher in the sky is the bright red star Antares in the constellation of Scorpius the Scorpion. Chart via John Jardine Goss/ EarthSky.

The instant of new moon is 20:53 UTC (2:53 p.m. CST) on January 21

January 22 evening: Venus and Saturn conjunction

Bright Venus and beautiful Saturn have a close conjunction on January 22, 2023. The planetary pair are only 0.4 degrees apart that evening. Venus will continue climbing higher in the sky each night, and Saturn will soon slip away from view. A very young waxing crescent moon – a little over a day old – hangs below the pair near the horizon. The lovely glow on the darkened portion of the moon is earthshine. Chart via John Jardine Goss/ EarthSky.

January 23 evening: Moon near Venus and Saturn

The thin waxing crescent moon shines low in the sky with Venus and Saturn after sunset on January 23, 2023. Venus emerged in the evening sky last month and will reach its greatest elongation from the sun on June 4, 2023. By the way, the beautiful glow you see on the unlit portion of the moon is earthshine. Saturn is poorly placed for viewing now and will be in conjunction with the sun on February 16, 2023. When is the last day you will see Saturn in the evening twilight? Chart via John Jardine Goss/ EarthSky.

January 25 and 26 evenings: Moon near Jupiter

The waxing crescent moon shines below Jupiter after sunset on January 25, 2023, and above the planet on January 26. Jupiter, the largest planet in our solar system, has been dominant in the evening sky for months and sets around 10 p.m. local time at the end of December. Chart via John Jardine Goss/ EarthSky.

The instant of 1st quarter moon is 15:19 UTC on January 28 (9:19 a.m. CST)

Mercury reaches greatest morning elongation on January 30 at 6 UTC (12 a.m.)

January 30 and 31 evenings: Moon near Mars

The waxing gibbous moon slides by Mars on the nights of January 30 and 31, 2023, then setting a few hours before sunrise. Another red object near Mars is the fiery red star Aldebaran, the Eye of Taurus the Bull. The eye-catching constellation of Orion the Hunter finishes out the cosmic scene. Chart via John Jardine Goss/ EarthSky.

December 2022 heliocentric solar system planets

The sun-centered charts below come from Guy Ottewell. You’ll find charts like these for every month of 2022 here, in his Astronomical Calendar. Guy Ottewell explains:

In these views from ecliptic north, arrows (thinner when south of the ecliptic plane) are the paths of the four inner planets. Dots along the rest of the orbits are five days apart (and are black for the part of its course that a planet has trodden since the beginning of the year). Also, semicircles show the sunlit side of the new and full moon (vastly exaggerated in size and distance). Additionally, pairs of lines point outward to the more remote planets.
Phenomena such as perihelia (represented by ticks) and conjunctions (represented by lines between planets) are at dates that can be found in the Astronomical Calendar. Likewise, gray covers the half of the universe below the horizon around 10 p.m. at mid-month (as seen from the equator). The zodiacal constellations are in directions from the Earth at mid-month (not from the sun).
