Step-by-step solution for: Time intervals in weeks and days worksheet
Let’s solve each question step by step using the calendars provided.
---
Question 1: We started our Home Learning on March 16. How many weeks and days have we been doing it until today (May 6)?
- Start date: March 16, 2020
- End date: May 6, 2020
Count the days:
From March 16 to March 31 = 16 days (including March 16? Let’s check: March 16 to March 31 is 16 days if you count both ends — but usually in these problems, “from A to B” means inclusive of start, exclusive of end? Wait — let’s think carefully.)
Actually, better to count total days between March 16 and May 6, then convert to weeks and days.
Use calendar:
- March has 31 days → from March 16 to March 31 = 16 days (if including March 16) → actually, from March 16 to March 31 inclusive is 16 days? Let's calculate:
March 16 to March 31:
31 - 16 + 1 = 16 days? But that includes both start and end. However, when counting "how long since", we usually don’t include the end day if it’s “until today”. But the problem says “until today (May 6)” — so likely includes May 6.
Better approach: Count total days from March 16 to May 6 inclusive? Or exclusive?
Standard way for “how many weeks and days have we been doing it until today” — means from start date up to and including today? Or not including today?
Actually, in school math, when they say “from date A to date B”, they often mean the number of days *between* them, not including the end date. But let’s test with actual calendar.
Let me count day-by-day or use a simpler method.
From March 16 to April 16 = exactly 4 weeks (28 days) → because March has 31 days, so March 16 to April 16 is 31 - 16 = 15 days in March, plus 16 days in April = 31 days? That can’t be right.
Wait — better:
Total days from March 16 to May 6:
- March: 31 - 16 = 15 days (after March 16, so March 17 to 31) → but if we include March 16, then it’s 16 days in March.
I think the safest is to assume “from March 16 to May 6” means the number of days elapsed, so:
Start: March 16
End: May 6
Days in March after March 16: March 17 to 31 → 15 days
Plus all of April: 30 days
Plus May 1 to May 6: 6 days
Total = 15 + 30 + 6 = 51 days
But wait — if we started on March 16, and today is May 6, how many full days have passed? From March 16 to May 6 inclusive would be more.
Actually, standard interpretation: If you start on Day 0 (March 16), then on March 17 it’s day 1, etc. So “how many days have we been doing it until May 6” means the number of days from March 16 to May 6, not including May 6? Or including?
This is confusing. Let’s look at the answer choices. The options are:
- May 25
- 3 weeks
- 7 weeks and 2 days
- May 3
- 4 weeks and 2 days
So for Q1, the answer should be one of these time intervals.
Let’s calculate properly.
From March 16 to May 6:
First, find how many days:
March 16 to March 31: 16 days (if including March 16) → no, from March 16 to March 31 inclusive is 16 days? 31 - 16 + 1 = 16 days.
But if we are counting duration, it’s better to do:
Number of days from March 16 to May 6 = (days in March after 16) + April + days in May up to 6.
If we consider March 16 as day 0, then:
- March 16 to April 16 = 31 days? No.
Let’s use a different method.
Calculate total days:
From March 16 to April 16 is exactly 4 weeks? Let’s see:
March 16 is Monday (from calendar: March 2020, 16 is Mon)
April 16 is Thursday? From April calendar: April 1 is Wed, so April 16 is Thu? Not same day.
Better to count total days.
March has 31 days.
From March 16 to March 31: 16 days (including 16th) — but for duration, if you start on 16th, by end of 16th, 1 day has passed? I think for this level, they mean the number of days between, not including start, including end? Or vice versa.
Perhaps easiest: use the fact that from March 16 to May 6 is 51 days if we exclude March 16 and include May 6? Let's calculate:
- March 17 to March 31: 15 days
- April 1 to April 30: 30 days
- May 1 to May 6: 6 days
Total: 15+30+6=51 days
51 days divided by 7 = 7 weeks and 2 days (since 7*7=49, 51-49=2)
Yes! 7 weeks and 2 days.
And that matches one of the options.
So Q1: 7 weeks and 2 days
---
Question 2: What is the date 6 weeks after March 22?
6 weeks = 42 days.
March 22 + 42 days.
March has 31 days, so from March 22 to March 31: 9 days (23 to 31 is 9 days, but if adding to 22, then 22 + 9 = 31, so 9 days gets us to March 31.
Then remaining days: 42 - 9 = 33 days into April and May.
April has 30 days, so 33 - 30 = 3 days into May.
So March 22 + 42 days = May 3.
Check: March 22 to April 22 is 31 days? March 22 to April 22 is exactly 4 weeks? 28 days? No.
March 22 to April 22: March has 31 days, so from March 22 to April 22 is 31 - 22 + 22 = 31 days? Better:
From March 22 to April 22 is 31 days only if March had 31 days, but actually:
Number of days from March 22 to April 22:
March 23 to 31: 9 days
April 1 to 22: 22 days
Total: 31 days — which is 4 weeks and 3 days, not 6 weeks.
We need 6 weeks = 42 days.
So from March 22:
Add 42 days.
March 22 + 9 days = March 31 (since 22 to 31 is 9 days later? 22+9=31, yes)
Remaining: 42 - 9 = 33 days
April has 30 days, so 33 - 30 = 3 days into May.
So May 3.
Yes.
From calendar: March 22 is Sunday (March 2020: 22 is Sun)
6 weeks later is also Sunday.
April 22 is Wednesday? April 1 is Wed, so April 22 is Wed + 21 days = Wed + 3 weeks = still Wed? 21 days is 3 weeks, so April 22 is Wed.
But we need 6 weeks from March 22.
March 22 (Sun) + 6 weeks = May 3? Let's see:
March 22 to March 29: 1 week → Sun
March 29 to April 5: 2nd week → Sun
April 5 to April 12: 3rd → Sun
April 12 to April 19: 4th → Sun
April 19 to April 26: 5th → Sun
April 26 to May 3: 6th → Sun
Yes! May 3 is Sunday, same as March 22.
So Q2: May 3

Question 3: Calculate the numbers of weeks between April 8 and April 29?
From April 8 to April 29.
Number of days: 29 - 8 = 21 days? But if inclusive, it might be different.
Usually, "between" means from April 8 to April 29, not including April 8? Or including?
In context, probably the number of days from April 8 to April 29, excluding start, including end? Or just difference.
29 - 8 = 21 days.
21 days / 7 = 3 weeks.
Exactly 3 weeks.
Check calendar: April 8 is Wednesday (April 2020: 8 is Wed)
April 29 is Wednesday? April 1 is Wed, so April 8 is Wed, April 15 Wed, April 22 Wed, April 29 Wed — yes, exactly 3 weeks later.
So Q3: 3 weeks
---
Question 4: What is the date 3 weeks and 3 days after May 1?
3 weeks = 21 days, plus 3 days = 24 days after May 1.
May 1 + 24 days.
May has 31 days, so May 1 + 24 days = May 25.
Because 1 + 24 = 25.
Check: May 1 is Friday (May 2020: 1 is Fri)
3 weeks later is May 22 (Fri), then +3 days = May 25 (Mon).
Yes.
So Q4: May 25
---
Question 5: Calculate the numbers of weeks and days between April 15 and May 15?
From April 15 to May 15.
April has 30 days, so from April 15 to April 30: 15 days (if excluding April 15, including April 30? Better to calculate total days.
From April 15 to May 15 is exactly one month, but months have different lengths.
April 15 to May 15:
April 16 to April 30: 15 days
May 1 to May 15: 15 days
Total: 30 days? But if including both ends, it might be 31 days.
Standard: number of days from April 15 to May 15.
If April 15 is day 0, then May 15 is day 30? Let's see.
From April 15 to May 15 is 30 days later? Because April has 30 days, so from April 15 to May 15 is 30 days.
Example: April 15 to April 16 is 1 day, ..., to May 15 is 30 days.
30 days divided by 7 = 4 weeks and 2 days (since 4*7=28, 30-28=2)
Check with calendar:
April 15 is Wednesday (April 2020: 15 is Wed)
May 15 is Friday? May 1 is Fri, so May 8 Fri, May 15 Fri — yes, Friday.
From Wed to Fri is 2 days extra.
Number of weeks: from April 15 to May 13 is 4 weeks? April 15 to April 22: 1 week, to 29: 2 weeks, to May 6: 3 weeks, to May 13: 4 weeks — then May 14 and 15 are two more days.
So 4 weeks and 2 days.
Yes.
So Q5: 4 weeks and 2 days
---
Now, matching to the drag options:
The options are:
- May 25 → for Q4
- 3 weeks → for Q3
- 7 weeks and 2 days → for Q1
- May 3 → for Q2
- 4 weeks and 2 days → for Q5
Perfect match.
Final Answer:
1. 7 weeks and 2 days
2. May 3
3. 3 weeks
4. May 25
5. 4 weeks and 2 days

Question 1: We started our Home Learning on March 16. How many weeks and days have we been doing it until today (May 6)?
- Start date: March 16, 2020
- End date: May 6, 2020
Count the days:
From March 16 to March 31 = 16 days (including March 16? Let’s check: March 16 to March 31 is 16 days if you count both ends — but usually in these problems, “from A to B” means inclusive of start, exclusive of end? Wait — let’s think carefully.)

Wait — better:
Total days from March 16 to May 6:
- March: 31 - 16 = 15 days (after March 16, so March 17 to 31) → but if we include March 16, then it’s 16 days in March.
I think the safest is to assume “from March 16 to May 6” means the number of days elapsed, so:
Start: March 16
End: May 6
Days in March after March 16: March 17 to 31 → 15 days
Plus all of April: 30 days
Plus May 1 to May 6: 6 days
Total = 15 + 30 + 6 = 51 days
But wait — if we started on March 16, and today is May 6, how many full days have passed? From March 16 to May 6 inclusive would be more.
Actually, standard interpretation: If you start on Day 0 (March 16), then on March 17 it’s day 1, etc. So “how many days have we been doing it until May 6” means the number of days from March 16 to May 6, not including May 6? Or including?
This is confusing. Let’s look at the answer choices. The options are:
- May 25
- 3 weeks
- 7 weeks and 2 days
- May 3
- 4 weeks and 2 days
So for Q1, the answer should be one of these time intervals.
Let’s calculate properly.
From March 16 to May 6:
First, find how many days:
March 16 to March 31: 16 days (if including March 16) → no, from March 16 to March 31 inclusive is 16 days? 31 - 16 + 1 = 16 days.
But if we are counting duration, it’s better to do:
Number of days from March 16 to May 6 = (days in March after 16) + April + days in May up to 6.
If we consider March 16 as day 0, then:
- March 16 to April 16 = 31 days? No.
Let’s use a different method.
Calculate total days:
From March 16 to April 16 is exactly 4 weeks? Let’s see:
March 16 is Monday (from calendar: March 2020, 16 is Mon)
April 16 is Thursday? From April calendar: April 1 is Wed, so April 16 is Thu? Not same day.
Better to count total days.
March has 31 days.
From March 16 to March 31: 16 days (including 16th) — but for duration, if you start on 16th, by end of 16th, 1 day has passed? I think for this level, they mean the number of days between, not including start, including end? Or vice versa.
Perhaps easiest: use the fact that from March 16 to May 6 is 51 days if we exclude March 16 and include May 6? Let's calculate:
- March 17 to March 31: 15 days
- April 1 to April 30: 30 days
- May 1 to May 6: 6 days
Total: 15+30+6=51 days
51 days divided by 7 = 7 weeks and 2 days (since 7*7=49, 51-49=2)
Yes! 7 weeks and 2 days.
And that matches one of the options.
So Q1: 7 weeks and 2 days
---
Question 2: What is the date 6 weeks after March 22?
6 weeks = 42 days.
March 22 + 42 days.
March has 31 days, so from March 22 to March 31: 9 days (23 to 31 is 9 days, but if adding to 22, then 22 + 9 = 31, so 9 days gets us to March 31.
Then remaining days: 42 - 9 = 33 days into April and May.
April has 30 days, so 33 - 30 = 3 days into May.
So March 22 + 42 days = May 3.
Check: March 22 to April 22 is 31 days? March 22 to April 22 is exactly 4 weeks? 28 days? No.
March 22 to April 22: March has 31 days, so from March 22 to April 22 is 31 - 22 + 22 = 31 days? Better:
From March 22 to April 22 is 31 days only if March had 31 days, but actually:
Number of days from March 22 to April 22:
March 23 to 31: 9 days
April 1 to 22: 22 days
Total: 31 days — which is 4 weeks and 3 days, not 6 weeks.
We need 6 weeks = 42 days.
So from March 22:
Add 42 days.
March 22 + 9 days = March 31 (since 22 to 31 is 9 days later? 22+9=31, yes)
Remaining: 42 - 9 = 33 days
April has 30 days, so 33 - 30 = 3 days into May.
So May 3.
Yes.
From calendar: March 22 is Sunday (March 2020: 22 is Sun)
6 weeks later is also Sunday.
April 22 is Wednesday? April 1 is Wed, so April 22 is Wed + 21 days = Wed + 3 weeks = still Wed? 21 days is 3 weeks, so April 22 is Wed.
But we need 6 weeks from March 22.
March 22 (Sun) + 6 weeks = May 3? Let's see:
March 22 to March 29: 1 week → Sun
March 29 to April 5: 2nd week → Sun
April 5 to April 12: 3rd → Sun
April 12 to April 19: 4th → Sun
April 19 to April 26: 5th → Sun
April 26 to May 3: 6th → Sun
Yes! May 3 is Sunday, same as March 22.
So Q2: May 3

Question 3: Calculate the numbers of weeks between April 8 and April 29?
From April 8 to April 29.
Number of days: 29 - 8 = 21 days? But if inclusive, it might be different.
Usually, "between" means from April 8 to April 29, not including April 8? Or including?
In context, probably the number of days from April 8 to April 29, excluding start, including end? Or just difference.
29 - 8 = 21 days.
21 days / 7 = 3 weeks.
Exactly 3 weeks.
Check calendar: April 8 is Wednesday (April 2020: 8 is Wed)
April 29 is Wednesday? April 1 is Wed, so April 8 is Wed, April 15 Wed, April 22 Wed, April 29 Wed — yes, exactly 3 weeks later.
So Q3: 3 weeks
---
Question 4: What is the date 3 weeks and 3 days after May 1?
3 weeks = 21 days, plus 3 days = 24 days after May 1.
May 1 + 24 days.
May has 31 days, so May 1 + 24 days = May 25.
Because 1 + 24 = 25.
Check: May 1 is Friday (May 2020: 1 is Fri)
3 weeks later is May 22 (Fri), then +3 days = May 25 (Mon).
Yes.
So Q4: May 25
---
Question 5: Calculate the numbers of weeks and days between April 15 and May 15?
From April 15 to May 15.
April has 30 days, so from April 15 to April 30: 15 days (if excluding April 15, including April 30? Better to calculate total days.
From April 15 to May 15 is exactly one month, but months have different lengths.
April 15 to May 15:
April 16 to April 30: 15 days
May 1 to May 15: 15 days
Total: 30 days? But if including both ends, it might be 31 days.
Standard: number of days from April 15 to May 15.
If April 15 is day 0, then May 15 is day 30? Let's see.
From April 15 to May 15 is 30 days later? Because April has 30 days, so from April 15 to May 15 is 30 days.
Example: April 15 to April 16 is 1 day, ..., to May 15 is 30 days.
30 days divided by 7 = 4 weeks and 2 days (since 4*7=28, 30-28=2)
Check with calendar:
April 15 is Wednesday (April 2020: 15 is Wed)
May 15 is Friday? May 1 is Fri, so May 8 Fri, May 15 Fri — yes, Friday.
From Wed to Fri is 2 days extra.
Number of weeks: from April 15 to May 13 is 4 weeks? April 15 to April 22: 1 week, to 29: 2 weeks, to May 6: 3 weeks, to May 13: 4 weeks — then May 14 and 15 are two more days.
So 4 weeks and 2 days.
Yes.
So Q5: 4 weeks and 2 days
