The table shows various locations and their time differences from UTC (Coordinated Universal Time), which is the same as GMT (Greenwich Mean Time).
| City or Country | Time Zone (UTC) | Other Locations |
|------------------|------------------|------------------|
| Hawaii | UTC – 10 hours | |
| Los Angeles, USA | UTC – 8 hours | |
| Guatemala | UTC – 6 hours | |
| New York, USA | UTC – 5 hours | |
| Saint Lucia | UTC – 4 hours | |
| Argentina | UTC – 3 hours | |
| England | UTC | |
| France | UTC + 1 hour | |
| Madagascar | UTC + 2 hours | |
| Nairobi | UTC + 3 hours | |
| Thailand | UTC + 7 hours | |
| China | UTC + 8 hours | |
| Japan | UTC + 9 hours | |
| Sydney, Australia| UTC + 10 hours | |
> Note: When a location is behind UTC (e.g., UTC – 5), it's earlier than UTC. When ahead (e.g., UTC + 1), it's later.

## ✔ Answering the Questions
- England = UTC
- Sydney = UTC + 10 hours
- So, add 10 hours to 10:30am → 8:30pm
✔ Answer: 8:30pm
---
- Hawaii = UTC – 10
- Saint Lucia = UTC – 4
- Difference: (-4) - (-10) = +6 hours → Saint Lucia is 6 hours ahead of Hawaii
- Add 6 hours to 2:30pm → 8:30pm
✔ Answer: 8:30pm
---
- Guatemala = UTC – 6
- France = UTC + 1
- Difference: (+1) - (-6) = +7 hours → France is 7 hours ahead
- Add 7 hours to 5:00pm → 12:00am (midnight)
✔ Answer: 12:00am (midnight)
---
- Greece = UTC + 1 (same as France)
- New York = UTC – 5
- Difference: (-5) - (+1) = -6 → New York is 6 hours behind
- Subtract 6 hours from midnight (12:00am) → 6:00pm (previous day)
✔ Answer: 6:00pm (the previous day)
---
- France = UTC + 1
- China = UTC + 8
- Difference: (+8) - (+1) = +7 → China is 7 hours ahead
- Add 7 hours to 8:30pm → 3:30am (next day)
✔ Answer: 3:30am (next day)
---
- Argentina = UTC – 3
- Pakistan = UTC + 5 (not listed, but standard time zone for Pakistan is UTC+5)
- Difference: (+5) - (-3) = +8 → Pakistan is 8 hours ahead
- Add 8 hours to 11:00am → 7:00pm
✔ Answer: 7:00pm
---
- Fiji = UTC + 12 (not listed, but standard for Fiji)
- Los Angeles = UTC – 8
- Difference: (-8) - (+12) = -20 → Los Angeles is 20 hours behind
- Subtract 20 hours from 1:37pm:
- 1:37pm minus 12 hours = 1:37am (same day)
- Minus another 8 hours = 5:37pm (previous day)
✔ Answer: 5:37pm (the previous day)
---
## ✔ Challenge Questions
- There are 360 degrees around the Earth.
- Each degree represents one line of longitude.
- So, there are 360 lines of longitude, spaced every 1 degree.
✔ Answer: 360 lines
---
- Russia has the most time zones — 11 time zones.
- It spans from UTC+2 (Kaliningrad) to UTC+12 (Kamchatka).
- (Note: Some sources say 11, others say 12 depending on inclusion of small regions.)
✔ Answer: Russia, 11 time zones
---
- The International Date Line is an imaginary line that runs roughly along the 180° longitude.
- It marks the boundary where one calendar day ends and another begins.
- When you cross it going east, you subtract a day.
- When you cross it going west, you add a day.
✔ Answer: The International Date Line is an imaginary line at approximately 180° longitude that separates one calendar day from the next.
---
- Examples:
1. United States – To save energy and make better use of daylight during summer months.
2. United Kingdom – To extend evening daylight in summer; called British Summer Time (BST).
3. Canada – Similar reasons: longer evenings in summer, energy conservation.
✔ Why? To align waking hours with daylight, reduce energy use, and improve safety and productivity.
---
- The ISS uses Coordinated Universal Time (UTC).
- This is because astronauts from different countries work together, and UTC provides a common reference.
✔ Answer: UTC (Coordinated Universal Time)
