Unit 14 Section 3 : Units of Time

In this section we explore the different units of time.

 1 minute = 60 seconds 1 hour = 60 minutes 1 day = 24 hours 1 week = 7 days 1 year = 365 days (or 366 in a leap year)

There are twelve months in one year, but the number
of days in each month varies. Also, some years are
leap years, which means that February has 29 days
instead of 28. This results in leap years having 366
days instead of the usual 365.

 January has 31 days February has 28 days (or 29 in a leap year) March has 31 days April has 30 days May has 31 days June has 30 days July has 31 days August has 31 days September has 30 days October has 31 days November has 30 days December has 31 days

Example Question

Example Question 1
How many hours are there in May?
There are 31 days in May, each with 24 hours.
31 × 24 = 744 so there are 744 hours in May.

Example Question 2
25 February is a Friday. What will the date be on the next Friday
(a) if it is not a leap year,
(b) if it is a leap year?

 We could just count on 7 days from the first date: Not in a leap year Start: Friday 25 +1: Saturday 26 February +2: Sunday 27 February +3: Monday 28 February +4: Tuesday 1 March +5: Wednesday 2 March +6: Thursday 3 March +7: Friday 4 March In a leap year Start: Friday 25 +1: Saturday 26 February +2: Sunday 27 February +3: Monday 28 February +4: Tuesday 29 February +5: Wednesday 1 March +6: Thursday 2 March +7: Friday 3 March We could also add on 7 to the first date, then take away the number of days in February: Not in a leap year 25 + 7 = 32 32 - 28 = 4 (4 March) In a leap year 25 + 7 = 32 32 - 29 = 3 (3 March) Either method above will allow you to find the answers.
