# Ticking Clocks and Turning Calendar
## Overview
This chapter introduces children to the concept of time, including leap years, reading calendars, identifying days and dates, understanding AM/PM, digital time formats, and measuring durations in hours and minutes. Students explore patterns in calendars, practice calculating durations, and enhance their ability to read both analog and digital clocks.
## Key Topics Covered
### 1. Leap Year and Calendars
- A leap year occurs every four years and has **366 days** instead of 365.
- **February in a leap year** has 29 days; otherwise, it has 28.

- Birthday-based questions used to calculate age and upcoming birthdays using the **DD/MM/YYYY** format.
### 4. Expiry and Manufacturing Dates
- Real-life application: Read **mfg. and exp. dates** on product wrappers (e.g., biscuit packets).
- Calculate how old the packet is and how long it remains safe to consume.
### 5. Monthly Patterns and Date-Day Analysis
- Activity to analyze what weekday falls on the 15th of different months.
- Encourage observation of **patterns in the calendar**.
### 6. Exploring Community Calendars
