Units of time (the ladder you must know cold)
| Seconds to minute | 60 seconds = 1 minute |
|---|---|
| Minutes to hour | 60 minutes = 1 hour (so 1 hour = 3600 seconds) |
| Hours to day | 24 hours = 1 day (= 1440 minutes = 86400 seconds) |
| Days to week | 7 days = 1 week; 14 days = 1 fortnight |
| Months & years | 12 months = 1 year; 10 yrs = decade; 100 yrs = century |
Clock angles & the leap-year rule
| Minute hand | sweeps 360 deg in 60 min = 6 deg per minute |
|---|---|
| Hour hand | sweeps 360 deg in 12 hr = 30 deg per hour = 0.5 deg per minute |
| One number gap | 5 minutes = 30 deg between two clock numbers |
| Common vs leap year | 365 days = 52 weeks + 1 day; 366 days = 52 weeks + 2 days |
| Leap-year test | divisible by 4; but a century (00) year only if divisible by 400 |
