NCERT Solutions for Class 4 Maths Chapter 12: Ticking Clocks and Turning Calendar

What this chapter teaches.
Reading a clock face for hours and minutes; the relationships 1 hour = 60 minutes, half hour = 30 minutes, quarter hour = 15 minutes; AM (before noon) and PM (after noon), and the 24-hour clock (where midnight = 00:00); reading a calendar — 12 months in a year, a week has 7 days, a year has 52 weeks; and leap years, which occur every 4 years and add an extra day (29 February) instead of the usual 28.

Given a calendar page, children find dates, count days between events, and identify the day of the week for a given date.
