Elapsed Time in Days worksheet - Free Printable

Let’s solve each question one by one, using the calendars provided.

---

Question 1:
Mavis is going on a field trip on November 12.
She needs to pay 4 days before that.

Count backward from November 12:
- 1 day before → Nov 11
- 2 days before → Nov 10
- 3 days before → Nov 9
- 4 days before → Nov 8

✔ So, she needs to pay on November 8.

---

Question 2:
She hands in her report 1 week after the trip (Nov 12).

1 week = 7 days.

Add 7 days to Nov 12:
- Nov 12 + 7 days = Nov 19

✔ Due date of the report is November 19.

Question 3:
Dennis’s bill is due on September 20.
He plans to pay a week before → that’s 7 days earlier.

Count back 7 days from Sept 20:
- Sept 20 - 7 = Sept 13

✔ He plans to pay on September 13.

---

Question 4:
He forgot and paid 5 days after the due date (Sept 20).

Add 5 days to Sept 20:
- Sept 20 + 5 = Sept 25

✔ He paid on September 25.

Question 5:
Spring break starts on March 15 and ends on March 23.

To find how long it is, count the days *including* both start and end dates? Or just the days between?

In school contexts, when we say “starts on X and ends on Y”, we usually include both days unless told otherwise.

So let’s count:

From March 15 to March 23 inclusive:

15, 16, 17, 18, 19, 20, 21, 22, 23 → that’s 9 days

But sometimes people mean “how many full days” or “duration”. Let’s check:

If you start on the 15th and end on the 23rd, the number of days *between* them is 8 days (not including start), but if you’re counting the total length of the break including both days, it’s 9.

Looking at typical school usage — spring break “from the 15th to the 23rd” means 9 days total.

Wait — let’s double-check with subtraction:

23 - 15 = 8 → but that doesn’t include the start day.

Actually, in calendar problems like this, if something starts on Day A and ends on Day B, the duration is (B - A + 1) days.

So: 23 - 15 + 1 = 9 days

✔ Spring break is 9 days long.

*(Note: Some might argue 8 days if they don’t count both ends — but since it says “starts on 15th and ends on 23rd”, and those are actual break days, we include both.)*

Question 6:
A report is sent home 5 days before spring break starts.

Spring break starts on March 15.

So subtract 5 days from March 15:

- March 15 - 5 = March 10

✔ Parents receive the report on March 10.

1. November 8
2. November 19
3. September 13
4. September 25
5. 9 days
