Compare Two Time Zones
Conquer Time Differences and Arrive Refreshed Wherever You Fly
We’ve all been there — landing after a long-haul flight only to feel like your body clock is stuck halfway across the world. That foggy, sluggish feeling is jet lag, and it can turn an exciting trip into a sleepy blur.
But don’t worry — with the right time zone strategies, smart planning, and a few handy travel products, you can outsmart jet lag and enjoy your journey from the very first day.
What Exactly Is Jet Lag?
Jet lag is your body’s response to rapidly crossing multiple time zones. Your internal clock — known as the circadian rhythm — struggles to match the new local time for sleep, eating, and alertness.
For example:
- Flying from New York to London (5-hour difference) makes your body think it’s dinner when locals are having breakfast.
- Traveling from India to California (12.5-hour difference) completely flips your day and night cycle.
Common jet lag symptoms include:
- Daytime fatigue or drowsiness
- Trouble falling asleep at night
- Irritability or lack of focus
- Mild headaches or digestion issues
The good news? You can reduce all of this with preparation and small behavioral tweaks — even before takeoff.
Adjusting Your Sleep Schedule Before You Fly
One of the best ways to prevent jet lag is to train your body clock early.
Here’s how:
- Shift bedtime gradually: Start sleeping 30–45 minutes earlier (for eastward flights) or later (for westward flights) a few days before your trip.
- Wake up at the destination’s sunrise time: Even while still home, align your alarm closer to your arrival time zone.
- Use light exposure: Bright light in the morning (for eastward travel) or in the evening (for westward travel) helps adjust your circadian rhythm.
🛏️ Pro tip: Bring a comfortable sleep mask or blackout curtain for your destination — darkness helps signal your brain that it’s bedtime, even when it’s bright outside.
Use the “One Hour per Day” Rule
A simple formula often used by frequent flyers and flight attendants:
➡️ It takes about one day to adjust for every time zone crossed.
So, if you cross six time zones, expect roughly six days before you’re fully synced — unless you actively use time management tricks like exposure to natural light and melatonin (when appropriate).
🕶️ Affiliate Tip: Try a melatonin sleep aid or jet lag supplement to help reset your internal clock gently.
Apps That Help You Adapt to New Time Zones
Modern travelers don’t have to rely on guesswork anymore. There are great apps that calculate your ideal sleep times, light exposure windows, and flight-based time shifts automatically.
Try these traveler-approved options:
- Timeshifter — scientifically backed app used by NASA astronauts and athletes.
- Entrain — helps you manage exposure to light for faster circadian adaptation.
- Sleep Cycle — tracks your sleep quality before and after your trip.
📱 Pair one of these apps with your own Time Zone Converter Tool on HoursIn.com to see exactly how local time compares before you land.
Manage Sleep In-Flight
Sleeping well during a flight can make or break your first few days abroad.
Here’s how to improve rest while cruising at 35,000 feet:
- Choose an aisle or window seat depending on your preference for movement or leaning support.
- Avoid caffeine or alcohol at least 3–4 hours before sleeping.
- Bring comfort essentials: A supportive neck pillow, travel blanket, and sleep mask make a huge difference.
🧳 Traveler’s Tip: Pack a memory foam neck pillow and a compact travel blanket.
Sync Your Watch Before Landing
About two hours before you land, set your watch and phone to the destination’s local time.
This psychological trick helps your mind start adjusting even before you arrive.
Also, if possible, plan your first meal and nap at the correct local times — not based on your departure schedule.

On Arrival: Light Is Your Secret Weapon
Light exposure plays a huge role in resetting your body clock.
- If you traveled eastward (ahead in time) → get morning light exposure.
- If you traveled westward (behind in time) → seek afternoon or evening light.
Try to get outside for at least an hour on your first day — sunlight suppresses melatonin and tells your body it’s daytime.
Hydration and Nutrition: Your Travel Allies
Cabin air is dry, and dehydration worsens jet lag symptoms.
Drink plenty of water, avoid heavy meals, and limit sugary snacks.
Electrolyte drinks can help restore balance, especially during long flights.
🥤 Affiliate idea: Carry a collapsible reusable water bottle or electrolyte powder pack for flights.
