Understanding Time

Time is a measurement that allows us to understand the sequence of events, the duration of activities, and the intervals between them. It is an essential concept in everyday life and can be represented in various units such as seconds, minutes, hours, days, weeks, months, and years.

Units of Time

There are several units of time that are commonly used:

• Seconds (s)
• Minutes (min)
• Hours (hr)
• Days (day)
• Weeks (wk)
• Months (mo)
• Years (yr)

Telling Time

Telling time involves expressing the current time of day using an analog clock (with hands) or a digital clock. The layout of a clock is based on a 12-hour cycle, with two rotations of the hour and minute hands each day.

AM and PM

Time is often divided into two 12-hour periods: AM (ante meridiem) and PM (post meridiem). AM refers to the hours from midnight until noon, while PM refers to the hours from noon until midnight.

Converting Units of Time

Converting between different units of time is an important skill. Here are some common conversions:

• 1 minute = 60 seconds
• 1 hour = 60 minutes
• 1 day = 24 hours
• 1 week = 7 days
• 1 month = approximately 30 days
• 1 year = 12 months

Elapsed Time

Elapsed time is the amount of time that has passed between two events. It is calculated by finding the difference between two given times or by adding or subtracting time intervals.
