Guide to Time Calculators

This hub covers everyday date and duration maths alongside tools built specifically for fly-in fly-out and shift work: swing rosters, timesheets, fatigue, travel packing and remote-site pay. The tricky part is that FIFO pay and time rarely work like a standard 9-to-5 — day rates, site allowances, roster-driven hours and tax treatment all interact, so the right tool depends on whether you are counting calendar days, tallying worked hours, or comparing take-home pay.

Dates, durations and countdowns

Use these for plain calendar maths: age-calculator and days-between-dates-calculator for elapsed time, date-add-subtract-calculator and business-days-calculator when weekends or working days matter, and countdown-calculator or time-duration-calculator for a target date or an interval between two times.

Rosters, shifts and hours worked

Start with fifo-roster-calculator to map a swing pattern (e.g. 8/6 or 2/1) across the calendar, then use shift-length-calculator and timesheet-calculator to total worked hours, and hours-to-decimal-calculator to convert time into decimal hours for pay.

Fatigue, sleep and travel

Reach for night-shift-rotation-calculator and sleep-debt-calculator to gauge recovery around shift changes and fatigue-break-calculator to plan rest on long drives, then fifo-pack-weight-calculator and baggage-weight-split-calculator to keep your bag within airline limits.

FIFO pay, allowances and take-home

Use hourly-rate-to-annual-fifo-salary-calculator and salary-vs-day-rate-comparison-calculator to weigh up a role, site-allowance-calculator and site-allowance-tax-impact-calculator to see what remote allowances add before and after tax, and swings-until-savings-goal-calculator to work out how many swings a savings target needs.
