We hope you enjoy your Night’n Day®.
This is a model of the Earth that accurately shows its orientation in
space with respect to the Sun at any time of day or year. Whether you
live in Paris or Cape Town, Night’n Day® shows the way the Earth
would look from space as it orbits the Sun and turns on its axis.
A precise gear and motor system turns the globe at the same rate that
the real Earth turns. It also reproduces how the northern and southern
hemispheres go through seasonal change.
Night’n Day® is a clock and calendar that shows the time of day and
date for any location on Earth. It also demonstrates which parts of the
Earth are in daylight. As the globe turns you can see where people on
Earth are experiencing sunrise, sunset and twilight times.
In summer and winter, the globe shows how much the hemisphere you
live in is tipped toward or away from the Sun. See for yourself how
polar regions experience 24-hour day and night in different seasons.
WARNING!
The LED lamp and holder
become hot during operation
– do not touch until they cool off.
CAUTION
Not recommended for children under 14 years of age. As with all electric products,
precautions should be observed during handling and use to prevent electric shock.

Before continuing, check the LED lamp. It is very bright. When it is on do
not look directly at it. Insert the AC adaptor plug into the jack in the
motor case and plug the power cord into an outlet. Push the square lamp
button on the base of the motor case. The lamp should come on. If it
doesn’t, push the button again. If the lamp still does not light, unplug
the cord, then push the lamp down into the socket – it might not be
making electrical contact. Plug the cord in again and push the button.
Push the button and turn off the lamp and unplug the globe.
7 - Attach the northern hemisphere
to the southern hemisphere.
The two halves fit together at
the equator around the Earth
globe. Make sure the continents
and lines of longitude line up.

ADJUSTMENTS
Setting the date and time
WHAT WILL YOUR GLOBE SHOW?
The globe turns at the same rate that the actual Earth is turning. It will show the
day of the year, time of day, and which parts of the Earth are in day and night.
HANDLING AND CLEANING
Do not put the globe or the motor base in water. Clean all surfaces with a slightly
damp soft cloth. Paper towels may scratch the clear plastic.
When moving the globe, lift it only by holding the motor base. Do not lift it by
holding the globe since it could come apart where the hemispheres join, or might
damage the motor connections.
1
1. Loosen the lock knob on the
support cup.
3
3. Tighten the lock knob on the
support cup.
4. Find your current time on the
Time Ring.
With both hands, Lift the southern hemisphere of the
globe and turn the globe slowly so that your location
on Earth lines up with the current time on the Time Ring.
2
2. Rotate the globe support cup so that the
pointer with red tip points at today’s date.

Note: Ensure both the locks
are perpendicular to the ring.
SOME TIPS ABOUT YOUR GLOBE’S
OPERATION
The lamp can be turned off with the square button. This will not turn off the
motor so your globe will continue to track the actual motion of the Earth.
The twilight strip on the lamp causes the line between day and night to be
slightly fuzzy, the way it is on the real Earth. The sunshade, which does not
move, causes the day and night effect by blocking the lamp. As your globe
turns, locations move into and out of the night side just as they do on Earth.
The line that divides the lit and unlit halves of the Earth is called the
terminator. When you are outside and see the Sun setting or rising, the
terminator is at your location. You can see the moon’s terminator when it is in
the sky.
Places that are on the same longitude line have the same solar time. For
example, find San Francisco and the longitude line closest to there. Look north
along the line until you come to Portland, Oregon. These are both at about
the same longitude. So if it is 8:00 am in San Francisco, it is 8:00 am in Portland.
The Time Ring is marked with hours and half hours. Estimating the correct
time to about 10 minutes is possible. Remember to correct for Daylight Savings
Time if it is kept in your area. Because the Earth’s speed in its orbit around the
Sun changes as the year goes by, the solar time on your globe may be off from
clock time by up to 10 to 15 minutes. This effect is called the Equation of Time.
5. To set the time as precisely as possible,
the longitude line nearest your location
should line up with the time on the
Time Ring. Once set, your globe should
only need minor adjustments every
couple of months, or when the power
to the globe is off.

SEASONS AND DATES
GLOSSARY
The Earth turns once on its axis in 24 hours with respect to the Sun. This is the day.
The movement is called rotation.
The Earth is also moving in its orbit around the Sun. This movement is called
revolution and one complete revolution around the Sun is the definition of the year.
The Earth takes 365.24 days to orbit the Sun once. The 0.24 days (approximately one
quarter of a day) is why we have leap years almost every four years. After four years
that quarter day adds up to one day. Calendars have whole days, not halves or
quarters, so three of four years have 365 days, and one, leap year has 366.
Because the extra bit is not exactly 0.25 days, leap years are not necessarily every
four years. If a year is divisible by four it is a leap year. If it is a century year (1800,
1900, 2000 etc.) it is a leap year only if it can be evenly divided by 400. So 2000 was a
leap year and the year 1900 was not.
The axis of the globe is tilted by 23.5º from being vertical. This is the same as the
actual planet. This angle is called the Obliquity of the Ecliptic.
The Earth’s tilt is always in the same direction. This results in the axis of the Earth
pointing to the same place in the northern and southern skies. In the northern skies,
the star Polaris is in line with the axis, which is why it appears to stay in the same
place during the night as the Earth turns.
The tilt of the Earth is also what causes seasons. When the northern hemisphere is
tipped toward the Sun, summer happens. The southern hemisphere would then be
tipped away from the Sun, so winter occurs there. The seasons flip when six months
later the northern half of the Earth is pointed away from the Sun, and the southern
half pointed toward the Sun.

DAY
The time it takes for the Earth to make one rotation on its axis with respect to
the Sun. The solar day = 24 hours. When the day is referenced against the
stars, the star day or sidereal day is 23 hours 56 minutes.
ECLIPTIC
An imaginary line that the Sun traces against the sky as the year passes. As the
Earth moves, or revolves around the Sun, our orbital motion makes the Sun
appear to move against the stars.

PARALLELS
Circles drawn around the Earth parallel to the equator. Parallels represent lines of
latitude. The parallel at Beijing is at latitude +40ºand goes around the Earth north of
and parallel to the equator. The parallel at Jakarta is at latitude of –6º and is drawn
parallel to and south of the equator.
POLAR CIRCLES
The parallels at latitude +66.5º and –66.5º are the Arctic and Antarctic Circles.
Areas north of the Arctic Circle experience 24-hour daylight in summer and 24-hour
night in winter. Areas south of the Antarctic Circle also see 24-hour day and night in
their respective summer and winter seasons.
SOLSTICE
The time of year when the Earth is at its maximum inclination toward or away from the
Sun. Each hemisphere has a summer solstice (tipped toward) and winter solstice (tipped
away). These occur on June 22
first day of summer in the northern hemisphere, and the first day of winter in the
southern hemisphere. December 22
nd
– 23rd and December 22nd – 23rd. June 22nd – 23rd is the
nd
– 23rd is the first day of winter in the north and
first day of summer in the south.
SUBSOLAR POINT
Point on the Earth where the Sun is shining directly overhead. This is also the point on
the Earth directly in line with the Sun and the center of the Earth. Only locations on the
Earth between latitude +23.5º and –23.5º can have the Sun directly overhead.
HOUR
An hour is 1/24
th
of a day or 60 minutes long. In an hour, the Earth turns 15º in
longitude. Each 15º segment is one time zone.
LATITUDE
The angular distance of a
Latitude 60º N
location from the equator
to the North or South
Latitude 30º N
Pole. The equator has
latitude = 0º. The North
Pole has latitude = +90º
and the South Pole is at

LONGITUDE
The angular distance east or west from the zero longitude meridian (at
Greenwich). Longitude goes from 0º to +180º as one heads east of Greenwich,
and 0º to –180º going west of Greenwich.
Meridians
Half circles that go around the Earth drawn from pole to pole. There are 24
meridians, and the spaces between them are the hourly time zones.
The meridian at Greenwich (0º longitude) is called the Prime Meridian.
The meridian at 180º is the International Date Line.
17 18
TIME ZONE
The segment between two meridians separated by 15º. For example, from 0º (Prime
Meridian) to +15º longitude is the first time zone. Each of these segments is 1/24 of the
Earth’s circumference, hence each represents a one hour time zone.
TROPICS
Area on Earth between the two parallels at latitude +23.5º and –23.5º. The northern
tropic is the Tropic of Cancer and the southern is the Tropic of Capricorn. The tropics
region is the only place where the Sun can be directly overhead during the year.
YEAR
The time for the Earth to orbit the Sun once, or to make one complete revolution
around the Sun. The year = 365.2425 days or 365 days and 5.8 hours. Since the year is
not an even 365 days, the extra 5.8 hours add up to almost one day after four years.
That is the origin of a leap year of 366 days.
