The day · N'Djamena, Chad
Night · 320 min left
Sun 83.2° below the horizon, in the north · Sahel & Sudanian Savanna
The kind of day it is
Heat
Hot. Growth is fast and stressed, trout and salmon retreat to springs and depth, and the useful hours are at the two ends of the day.
Water deeply at dusk, not at noon. Fish the springs, the shade and the depth.
The day, phase by phase
Happening now · 18:32–05:04
10h 32m long
Night
Where the sun is this minute. Its highest today: 72.7°.
No solar input at all. What happens now runs on stored heat, on the moon, and on the animals that evolved to work while nothing can see them.
In the water now
Nothing much is moving in the water in this phase.
Warm water holds less oxygen. Fish the springs, the inflows and the deep water, and release quickly.
In the garden now
Ground beetlebest now
Running the soil surface after dark, taking slugs, cutworms and larvae. One of the best predators a garden has.
Earthwormbest now
At the surface after dark and in wet weather, pulling leaves down into the burrow.
Slugsbest now
Out on everything, feeding hardest between midnight and first light, and all day when it is wet.
Above about 32 °C tomatoes drop their flowers and lettuce turns bitter.

Try it
Spin the Earth — and bring the day to N'Djamena
Drag the Earth round, or tap the arrows, and watch home turn into the sunlight at sunrise, round to noon, away again at sunset, and through the night. One whole turn is one day and one night.
Night at home
Still dark. Keep turning — home is coming round toward the sunlight.
One whole turn = 24 hours
Turn to:
Seen from above the North Pole, the Earth turns anticlockwise — west to east — so the Sun comes up in the east. One whole turn takes 24 hours.
Say it like this
- Age 2“Round and round! Where is our house? Is it day or night?”
- Age 4“When our house turns toward the Sun, it's day. When it turns away, it's night.”
- Age 6“The Sun doesn't really move across the sky — we do, riding on the turning Earth. How many hours does one whole turn take?”
Go outside: Stand in the same spot at breakfast, lunch and supper and point to where the Sun is — never look straight at it. It moves from east to west because we are turning.
