Unit 1

About this unit
Master the art of counting sessions, events, and earnings across real calendar periods. You will work with date ranges, weekday patterns, public holidays, and irregular schedules to answer precise numerical questions about time.
What types of questions will you face?
- 1Count total sessions held over a date range, accounting for specific days of the week
- 2Calculate total earnings when different days attract different pay rates
- 3Find the day of the week for a future date using a given starting day
- 4Determine how many performances or classes occur given a weekly schedule and a cancellation
- 5Work out which dates fall on specific weekdays within a given month
Skills you will build
- Converting days into weeks and counting remainder days accurately
- Applying weekday cycling (7-day rotation) to project into the future
- Tracking exclusions and special cases within a date range
- Multi-step arithmetic combining counts, rates, and totals
- Reading and interpreting schedule tables with multiple conditions
By the end of this unit, you will be able to
- Calculate session counts over any calendar period without a physical calendar
- Compute earnings where different days have different rates and some days are excluded
- Work out the exact day of the week for a date far in the future
- Solve real-life scheduling problems accurately under time pressure
Difficulty profile
Questions in this unit are mostly Very Easy to Easy. They reward careful, methodical counting more than advanced reasoning — making this an ideal starting unit to build confidence.
Exam tip: Calendar and Date Counting
Always list out the weeks explicitly when counting sessions. A quick week-by-week tally is faster and less error-prone than trying to calculate totals in your head.
