Question 1.
Notice the number of days in February in the Years 2024 and 2025.
Number of days in Feb 2024 = ______
Number of days in Feb 2025 = ______
Answer:
Number of days in February 2024 = 29
Number of days in February 2025 = 28
Question 2.
Fill in the blanks with consecutive leap years before and after 2024. ______ , ______ , 2024, ______ , ______ , ______ –
Answer:
Leap years happen every 4 years.
To find the leap year before 2024, we subtract 4: 2024 – 4 = 2020. The leap year before 2020 is 2016 (2020-4 = 2016).
To find the next leap year after 2024, we add 4:2024 + 4 = 2028.
The leap year after 2028 will be 2028 + 4 = 2032.
The leap year after 2032 is 2036 (2032 + 4 = 2036).
So, the consecutive leap years are: 2016, 2020, 2024, 2028, 2032, 2036.
Question 3.
We know that most years have 365 days. How many days would a leap year have?
Answer:
As we saw with February 2024 having 29 days instead of the usual 28, a leap year has one extra day.
So, a leap year has 365+1=366 days.
Question 4.

Answer:
| Name of the Festival | Name of the Month |
| Holi | March |

Answer:
(a) Today : Friday
(b) Yesterday : Thursday
(c) Tomorrow : Saturday
(d) Day after tomorrow : Sunday
(e) Day before yesterday: Wednesday
Question 6.
July 1 is a Monday. Write the dates for the next two Mondays.
Answer:
There are 7 days in a week, so the next Monday will be 7 days after July 1st.
First next Monday: July 1 + 7 = 8
Second next Monday: July 8 + 7 = 15
So, the dates for the next two Mondays are July 8 and July 15.
Question 7.
Laali is born on 04 / 07 / 2014 and Chotu is born on 04 / 12 / 2019. Who is older among the two and how much?
Laali will turn 5 years old on ______。
Chotu’s 10th birthday will be celebrated on ______ .
Answer:
Laali’s birth date: 04/07/2014
Chotu’s birth date: 04/12/2019
To find out who is older, we look at their birth years first. Laali was born in 2014, and Chotu was born in 2019. Since 2014 comes before 2019, Laali is older than Chotu.
Now, let’s calculate the age difference.
From 04/07/2014 to 04/07/2019, that’s exactly 5 years. Chotu was born on 04/12/2019, which is 5 months after July (August, September, October, November, December).
So, Laali is older than Chotu by 5 years and 5 months.
→ Now, let’s answer the other parts:
Laali will turn 5 years old on:
Laali was born on 04 / 07 / 2014. To find when she turns 5 , we add 5 years to her birth year:
2014 + 5 = 2019
So, Laali will turn 5 years old on 04/07/2019.
→ Chotu’s 10th birthday will be celebrated on:
Chotu was born on 04/12/2019. To find his 10th birthday, we add 10 years to his birth year:
2019 + 10 = 2029
So, Chotu’s 10th birthday will be celebrated on 04/12/2029.
Question 8.

(a) How old is the packet of biscuits?

Question 9.
Notice the day on which July 15 falls in your calendar. Now find out what day is August 15? September 15? October 15? What pattern do you notice? Share in grade.
Now choose a date and look up the day on which it falls. Challenge your friends to guess what day will the same date fall in the following month.
Answer:
15th of each Month in 2025
| Month | Date | Day of the Week |
| July | July 15, 2025 | Tuesday |
| August | August 15, 2025 | Friday |
| September | September 15, 2025 | Monday |
| October | October 15, 2025 | Wednesday |
What pattern do we notice?
The 15th of each month falls on different days of the week.
For example:
- July 15 is a Tuesday.
- August 15 is a Friday.
- September 15 is a Monday.
- October 15 is a Wednesday.
This variation occurs because months have different numbers of days, and the calendar progresses accordingly.

Raghav brings milk from the market every morning.
Raghav leaves home at 8:20 AM and returns back at 8:35 AM.
