Time Around the World Worksheet | Time Zones | Twinkl - Free Printable

It looks like you've uploaded an image of a worksheet about international time zones. The task involves understanding time differences between various cities around the world and solving problems related to converting times across these zones.

Let’s go step by step to solve the problem and explain the solution based on what we can see in the image.

🔍 Understanding the Worksheet

The left side shows clocks with times for different cities, each labeled with their time zone offset from UTC (Coordinated Universal Time):

| City | Time Zone Offset |
|--------------|------------------|
| Los Angeles | -8 |
| Calgary | -7 |
| New York | -5 |
| Brasília | -4 |
| Dublin | +0 |
| Paris | +1 |
| Moscow | +3 |
| Beijing | +7 |
| Sydney | +11 |

Each city has:
- A clock showing the current local time.
- A digital display below it showing the same time.

For example:
- Los Angeles (-8): Clock shows 4:00
- New York (-5): Clock shows 1:00

This means that when it's 4:00 AM in Los Angeles, it's 1:00 AM in New York? Wait — let's check this carefully.

Actually, since New York is 3 hours ahead of Los Angeles (because -5 vs -8), if it's 4:00 in LA, then it should be 7:00 in New York.

But the clock in New York shows 1:00, not 7:00.

Wait — perhaps the clocks are all showing the same moment in time, but in different time zones?

Let’s look at the times shown:

| City | Time Shown |
|--------------|------------|
| Los Angeles | 4:00 |
| Calgary | 5:00 |
| New York | 1:00 |
| Brasília | 8:00 |
| Dublin | 12:00 |
| Paris | 13:00 |
| Moscow | ? |
| Beijing | ? |
| Sydney | ? |

Wait — there’s inconsistency here. Let's verify whether these times make sense if they're all simultaneous.

Let’s suppose the reference point is UTC (Zulu time).

We’ll convert each city's displayed time to UTC and see if they align.

---

🧮 Step 1: Convert Each Displayed Time to UTC

Use formula:
UTC = Local Time - Time Zone Offset

| City | Local Time | Offset | UTC Time |
|-------------|------------|--------|----------|
| Los Angeles | 4:00 | -8 | 4:00 + 8 = 12:00 UTC |
| Calgary | 5:00 | -7 | 5:00 + 7 = 12:00 UTC |
| New York | 1:00 | -5 | 1:00 + 5 = 6:00 UTC ✘ Not matching! |

Uh-oh — inconsistency.

Wait — if Los Angeles is 4:00, UTC is 12:00.

Calgary is -7, so at 12:00 UTC, Calgary should be 5:00 → ✔ matches.

New York is -5 → at 12:00 UTC, New York should be 7:00 AM, but the clock shows 1:00 → ✘ mismatch.

So either:
- The clocks are not synchronized to the same moment, or
- There’s a typo, or
- We need to interpret differently.

Wait — maybe the times shown are not all simultaneous? But the layout suggests they are.

Alternatively, perhaps the digital times are correct, and the analog clocks are just representations.

Looking again:

- Los Angeles: 4:00 → 4:00 AM?
- Calgary: 5:00 → 5:00 AM?
- New York: 1:00 → 1:00 AM?

But that would mean:
- When it’s 4:00 AM in LA, it’s 5:00 AM in Calgary (+1 hour) → correct.
- Then New York should be 7:00 AM, but it shows 1:00 → impossible.

Unless it's 1:00 PM, i.e., 13:00.

Ah! Maybe the digital display is 24-hour format, and the analog clock is ambiguous.

Look at Dublin: digital says 12:00, analog shows 12:00 → could be noon.

Paris: digital says 13:00, analog shows 1:00 → consistent.

So likely:
- All times are in 24-hour format, and the clocks show the same moment.

Let’s assume the current time is such that all these times are valid simultaneously.

Let’s pick one city as reference.

Try Dublin (UTC+0): digital shows 12:00 → so 12:00 UTC.

Now check others:

| City | Offset | UTC | Local Time |
|-------------|--------|-----|------------|
| Dublin | +0 | 12:00 | 12:00 ✔ |
| Paris | +1 | 12:00 | 13:00 ✔ |
| Los Angeles | -8 | 12:00 | 4:00 ✔ (12:00 - 8 = 4:00) |
| Calgary | -7 | 12:00 | 5:00 ✔ |
| New York | -5 | 12:00 | 7:00 ✘ but shows 1:00 |

Wait — New York should be 7:00 AM, but the digital display says 01:00 → that’s 1:00 AM.

That’s a problem.

But wait — the digital display under New York says 01:00, but the analog clock shows 1:00, which could be 1:00 AM or PM.

But if UTC is 12:00, New York is -5 → 7:00 AM.

So why does it show 1:00?

Hmm.

Wait — perhaps the digital display is not 24-hour, or the time is not 12:00 UTC?

Let’s try another approach.

Suppose New York shows 1:00, and its offset is -5.

Then UTC = 1:00 + 5 = 6:00 UTC

Now check others:

| City | Offset | UTC | Local Time |
|-------------|--------|-----|------------|
| New York | -5 | 6:00 | 1:00 ✔ |
| Los Angeles | -8 | 6:00 | 6:00 + 8 = 14:00 → 2:00 PM |
But Los Angeles shows 04:00 → 4:00 AM or PM? Digital says 04:00 → likely 4:00 AM.

But 4:00 AM ≠ 2:00 PM → conflict.

So not possible.

Wait — maybe the digital times are 24-hour, and the analog clocks are wrong?

No — analog clocks seem accurate.

Wait — look at Brasília (-4): shows 08:00

If UTC is X, then Brasília = X - 4 = 8:00 → X = 12:00 UTC

So UTC = 12:00

Now check:

- Los Angeles (-8): 12:00 - 8 = 4:00 → shows 04:00 ✔
- Calgary (-7): 12:00 - 7 = 5:00 → shows 05:00 ✔
- New York (-5): 12:00 - 5 = 7:00 → but shows 01:00 ✘

Still doesn’t work.

Unless… the New York time is 1:00 PM, i.e., 13:00, but digital says 01:00 — that’s confusing.

Wait — digital displays:

- Los Angeles: 04:00
- Calgary: 05:00
- New York: 01:00
- Brasília: 08:00
- Dublin: 12:00
- Paris: 13:00

If we assume all digital times are in 24-hour format, then:

- New York: 01:00 → 1:00 AM
- Dublin: 12:00 → 12:00 PM (noon)
- Paris: 13:00 → 1:00 PM

But Paris is +1, Dublin is +0 → so Paris should be 1 hour ahead of Dublin.

If Dublin is 12:00, Paris should be 13:00 → ✔

So if Dublin is 12:00 (noon), then UTC = 12:00

Then New York (-5): 12:00 - 5 = 7:00 → should be 7:00 AM, but shows 01:00 → not matching.

But if New York shows 01:00, and it’s 1:00 AM, then UTC = 1:00 + 5 = 6:00 UTC

Then Dublin (UTC+0): 6:00 → should be 6:00 AM, but shows 12:00 → no.

So contradiction.

Wait — unless the digital times are not all at the same moment? That seems unlikely.

Alternative idea: perhaps the times shown are not the current time, but rather examples.

But the worksheet asks to “complete the sentences” and “fill in the table”.

Let’s look at the right side.

---

✔ Right Side: Task Instructions

There’s a section titled "Complete the sentences":

1. Dublin is ____ hours ___ of New York.
2. Dublin is ____ hours ___ of Paris.
3. Paris is ____ hours ___ of Dublin.
4. Sydney is ____ hours ___ of Los Angeles.
5. Calgary is ____ hours ___ of Dubai.
6. ____ is 13 hours behind Tokyo.
7. ____ is 1 hour ahead of Dublin.

And a table to fill in meeting times.

Also, a watch shows 0:52 — possibly indicating a time difference?

And a plane flying — maybe indicating travel?

And a list of cities with times:

- New York (-5): 01:00
- Paris (+1): 13:00
- Sydney (+11): 01:00

Wait — Sydney (+11) shows 01:00, same as New York?

That can't be.

But if New York is 01:00, and Sydney is +11, then Sydney should be 01:00 + 16 = 17:00 (5:00 PM)

But it shows 01:00 → impossible.

Unless it's different days.

But still, the digital time is 01:00, which is 1:00 AM.

So if New York is 1:00 AM, UTC = 1:00 + 5 = 6:00 UTC

Sydney is +11 → 6:00 + 11 = 17:00 → 5:00 PM

But Sydney shows 01:00 → conflict.

So the only way this works is if the times shown are not simultaneous.

But the layout suggests they are.

Wait — perhaps the digital times are examples, and the analog clocks are just illustrations.

But the task is to use the information to solve time zone problems.

Let’s focus on the sentences.

🔎 Solving the Sentences

We have time zones:

- Los Angeles: -8
- Calgary: -7
- New York: -5
- Brasília: -4
- Dublin: +0
- Paris: +1
- Moscow: +3
- Beijing: +7
- Sydney: +11

Now answer:

1. Dublin is ____ hours ___ of New York.

Dublin: +0
New York: -5
Difference: 0 - (-5) = +5 → Dublin is 5 hours ahead of New York.

✔ Answer: 5 hours ahead

2. Dublin is ____ hours ___ of Paris.

Dublin: +0
Paris: +1
So Dublin is 1 hour behind Paris.

✔ Answer: 1 hour behind

3. Paris is ____ hours ___ of Dublin.

Paris is 1 hour ahead of Dublin.

✔ Answer: 1 hour ahead

4. Sydney is ____ hours ___ of Los Angeles.

Sydney: +11
Los Angeles: -8
Difference: 11 - (-8) = 19 hours → Sydney is 19 hours ahead of Los Angeles.

✔ Answer: 19 hours ahead

5. Calgary is ____ hours ___ of Dubai.

Calgary: -7
Dubai: ??? — not listed.

Wait — Dubai is not on the list.

But in the table, there’s a column for "Dubai".

And in the time zone list, we don’t have Dubai.

But we do have Moscow (+3), Beijing (+7), Sydney (+11)

Perhaps Dubai is +4?

Yes — typically, Dubai is UTC+4.

So Calgary (-7), Dubai (+4)

Difference: 4 - (-7) = 11 hours → Dubai is 11 hours ahead of Calgary.

So Calgary is 11 hours behind Dubai.

✔ Answer: 11 hours behind

6. ____ is 13 hours behind Tokyo.

Tokyo is usually UTC+9

So city that is 13 hours behind Tokyo: 9 - 13 = -4 → UTC-4

Look at our list: Brasília is -4

✔ Answer: Brasília

7. ____ is 1 hour ahead of Dublin.

Dublin is +0 → +1 is Paris

✔ Answer: Paris

✔ Final Answers to Sentences:

1. Dublin is 5 hours ahead of New York.
2. Dublin is 1 hour behind of Paris.
3. Paris is 1 hour ahead of Dublin.
4. Sydney is 19 hours ahead of Los Angeles.
5. Calgary is 11 hours behind of Dubai.
6. Brasília is 13 hours behind Tokyo.
7. Paris is 1 hour ahead of Dublin.

📊 Table: Meeting Times

The table has:

| City | Los Angeles | Calgary | New York | Brasília | Dubai | Paris | Moscow | Beijing | Sydney |
|------------|-------------|---------|----------|----------|-------|-------|--------|---------|--------|
| 01:00 | | | | | | | | | |
| 21:45 | | | | | | | | | |

And instruction: "Figure out the correct time for each meeting."

So probably, if a meeting is at 01:00 in Los Angeles, what time is it in other cities?

Similarly for 21:45.

We need to convert using time zone offsets.

Let’s do both rows.

#### Row 1: Meeting at 01:00 in Los Angeles (UTC-8)

Convert to UTC: 01:00 + 8 = 09:00 UTC

Now convert to other cities:

- Calgary (-7): 09:00 - (-7)? No: UTC + offset → 09:00 + (-7) = 02:00 → 02:00
- New York (-5): 09:00 + (-5) = 04:00 → 04:00
- Brasília (-4): 09:00 - 4 = 05:00 → 05:00
- Dubai (+4): 09:00 + 4 = 13:00 → 13:00
- Paris (+1): 09:00 + 1 = 10:00 → 10:00
- Moscow (+3): 09:00 + 3 = 12:00 → 12:00
- Beijing (+7): 09:00 + 7 = 16:00 → 16:00
- Sydney (+11): 09:00 + 11 = 20:00 → 20:00

So row 1:

| City | Los Angeles | Calgary | New York | Brasília | Dubai | Paris | Moscow | Beijing | Sydney |
|------------|-------------|---------|----------|----------|-------|-------|--------|---------|--------|
| 01:00 | 01:00 | 02:00 | 04:00 | 05:00 | 13:00 | 10:00 | 12:00 | 16:00 | 20:00 |

#### Row 2: Meeting at 21:45 in Los Angeles

Convert to UTC: 21:45 + 8 = 05:45 next day (21:45 + 8 = 29:45 → 05:45)

Now convert:

- Calgary (-7): 05:45 + (-7) = -1:15 → add 24 → 22:45
- New York (-5): 05:45 - 5 = 00:45 → 00:45
- Brasília (-4): 05:45 - 4 = 01:45 → 01:45
- Dubai (+4): 05:45 + 4 = 09:45 → 09:45
- Paris (+1): 05:45 + 1 = 06:45 → 06:45
- Moscow (+3): 05:45 + 3 = 08:45 → 08:45
- Beijing (+7): 05:45 + 7 = 12:45 → 12:45
- Sydney (+11): 05:45 + 11 = 16:45 → 16:45

So row 2:

| City | Los Angeles | Calgary | New York | Brasília | Dubai | Paris | Moscow | Beijing | Sydney |
|------------|-------------|---------|----------|----------|-------|-------|--------|---------|--------|
| 21:45 | 21:45 | 22:45 | 00:45 | 01:45 | 09:45 | 06:45 | 08:45 | 12:45 | 16:45 |
