How to Use the Sun to Tell Time

Why Should You Learn How to Use the Sun to Tell Time?

There’s something satisfying about knowing how to tell time without depending on your watch or phone. It connects you to the earth’s rhythms. Plus, it’s a neat party trick—who wouldn’t be impressed if you glance at the sky, squint, and confidently say, “Ah, it’s about 3 PM”?

Not only is it handy for outdoor adventures, but learning how to use the sun to tell time can also make you more mindful of nature. We’ve grown so accustomed to modern conveniences that we often forget the simple ways people once lived—like figuring out the time by simply looking up.

The Basics: How the Sun’s Position Tells Time

The sun rises in the east, peaks in the south (if you’re in the Northern Hemisphere), and sets in the west. This regular pattern gives us the perfect tool for estimating time. Before clocks and fancy technology, civilizations depended on this daily journey. You can, too, if you understand a fewfundamentaly principles.

Morning Hours: The Sun Rises in the East

At dawn, when the sun peeks over the horizon in the east, it’s roughly 6 AM. However, the exact time of sunrise depends on the season and your location. In winter, for instance, the sun might rise as late as 8 AM, while in the summer, it could be up by 5 AM. Still, as a general rule, you can consider the early hours as morning whenever the sun is in the east.

Midday: Solar Noon

When the sun reaches its highest point in the sky, it’s solar noon. This doesn’t always align with noon on your clock because time zones and Daylight Saving Time mess with nature’s schedule. But at solar noon, the sun is directly overhead (or as close as it’ll get), casting the shortest shadow of the day.

Afternoon: The Westward Journey

As the day progresses, the sun begins to descend, moving westward. By the time it’s closer to the horizon, you know you’re nearing the late afternoon or early evening. Depending on how high the sun is in the sky, you can estimate whether it’s 3 PM or 5 PM.

Your Shadow: A Natural Timepiece

When was the last time you noticed your shadow? It turns out it’s not just for playing Peter Pan or seeing if groundhogs predict the weather. Your shadow is one of the best tools for telling time using the sun.

Shorter Shadows Mean It’s Around Midday

As the sun rises higher in the sky, your shadow shortens. When your shadow is at its shortest, it’s probably around noon. You can then use the lengthening of your shadow as the afternoon progresses to estimate the time.

How to Use Your Hand to Gauge Time

Here’s a trick you’ll love: hold your hand up to the horizon with your fingers spread out. Count the number of fingers between the horizon and the sun. Each finger-width represents about 15 minutes. So, if you can fit four fingers between the sun and the horizon, you’ve got about an hour until sunset.

Using a Stick to Create a Makeshift Sundial

Grab a stick and create your sundial if you’re feeling a bit more adventurous. This method requires a little patience, but it’s incredibly accurate.

Step-by-Step Guide to Making a Stick Sundial

1. Find a straight stick (around 2-3 feet long works best).
2. Place it upright in the ground, where it’ll get direct sunlight.
3. Every hour, mark the end of the shadow cast by the stick. After a few hours, you’ll see a pattern of the sun’s movement.
4. Connect the marks to create a rough guide for time as the shadow moves throughout the day.

While this method won’t give you the minute-by-minute precision of your smartphone, it’s a reliable way to estimate the time, especially if you’re in a pinch.

Seasonal Changes: How the Sun’s Path Varies by Month

One thing to remember when telling time by the sun is that it doesn’t always behave the same way. During the winter, the sun’s arc is lower in the sky, which means shorter days and longer shadows. In summer, the sun takes a higher path, leading to longer days and shorter shadows around midday.

How to Adjust for Different Seasons

• Summer: Expect earlier sunrises and later sunsets. Noon shadows will be pretty short.
• Winter: Late sunrises and early sunsets mean shadows stay longer throughout the day.

To adapt your solar time-reading skills to different seasons, remember the sun’s position will be higher in summer and lower in winter.

Why Understanding Solar Time Is Still Relevant Today

You might be wondering: with all our technology at our fingertips, why bother learning how to use the sun to tell time? Here’s why: technology fails. Phones run out of battery. Watches break. But the sun? It’s always there (unless it’s cloudy…but that’s a different issue).

Telling time by the sun also keeps you in sync with nature, fostering a deeper understanding of your environment. This skill ties us to our ancestors, who navigated their days using nothing more than the natural world around them.

Common Challenges When Using the Sun to Tell Time

Of course, nothing’s perfect, and the sun isn’t always the easiest timekeeper to rely on. Clouds, mountains, and trees can all obscure your view, making judging the sun’s position trickier. If you’re in a place with tall buildings or heavy forest cover, you might have to be creative and find a clearing to see the sky.

How Accurate Is Solar Time Compared to a Clock?

While using the sun to tell time won’t be as precise as checking your phone, it’s surprisingly accurate if you practice. Expect to be off by about 15-30 minutes, depending on your method. But let’s be honest—if you’re relying on the sun for time, you’re probably not too worried about catching the bus at exactly 2:47 PM.
