Which Season is it? (Measurement of Time)

Given: The 2023 calendar provided.

Concept: Count the dates in each month from the calendar.

Working:
- January ends on 31, March ends on 31, May ends on 31, July ends on 31, August ends on 31, October ends on 31, December ends on 31. So these months have 31 days each.
- February ends on 28 (as seen in the calendar — the last date is 28). So February has 28 days.
- April ends on 30, June ends on 30, September ends on 30, November ends on 30. So these months have 30 days each.

Answer:

| Months | Number of days |
|---|---|
| January, March, May, July, August, October, December | 31 |
| February | 28 |
| April, June, September, November | 30 |

Answer: We use a calendar to keep track of days, weeks, months, and the year. It helps us remember important dates like birthdays, holidays, festivals, and school events. It also helps us plan our activities in advance.

Answer: No, February does not have the same number of days every year.
- In most years, February has 28 days.
- Every 4 years, there is a Leap Year in which February has 29 days.
- A leap year is a year that is divisible by 4 (for example, 2024 is a leap year).

So February can have either 28 or 29 days depending on the year.

Answer: There are 7 days in a week.

(Sunday, Monday, Tuesday, Wednesday, Thursday, Friday, Saturday)

Given: April 2023 calendar.

Working: Looking at the April calendar, the Sundays fall on: 2, 9, 16, 23, 30.

Answer: There are 5 Sundays in the month of April.

Given: The 2023 calendar.

Working: Count the Sundays in each month:
- January: Sundays on 1, 8, 15, 22, 29 → 5 Sundays
- April: Sundays on 2, 9, 16, 23, 30 → 5 Sundays
- July: Sundays on 2, 9, 16, 23, 30 → 5 Sundays
- October: Sundays on 1, 8, 15, 22, 29 → 5 Sundays
- December: Sundays on 3, 10, 17, 24, 31 → 5 Sundays

Answer: January, April, July, October, December have 5 Sundays.

Answer: Summer vacations are in the months of May and June.

(Note: This may vary slightly by school, but typically summer vacations in India fall in May and June.)

Answer: Winter vacations are in the months of December and January.

(Note: This may vary by school, but typically winter vacations fall in December and January.)

Given: April has 30 days; March has 31 days.

Working:
$$30 + 31 = 61$$

Answer: $30$ days $+$ $31$ days $=$ 61 days.

Concept: We match each activity to the most appropriate unit of time based on how long it typically takes.

Answer:

| Activity | Duration |
|---|---|
| Yoga | Hours (usually 1 hour) |
| Playing | Hours (usually 1–2 hours) |
| Cooking | Hours (usually 1–2 hours) |
| Filling a water tank | Hours (a few hours) |
| Knitting a sweater | Days (several days) |
| Summer vacation | Months (about 2 months) |
| Seed to grow into a plant | Months (several months) |
| Change of season | Months (about 3 months per season) |

Summary: Activities like Yoga, Playing, Cooking, and Filling a water tank take Hours. Knitting a sweater takes Days. Summer vacation, Seed growing into a plant, and Change of season take Months.
