Formula
days = ceil((payday − from date) in milliseconds ÷ ms per day)
Subtract the start date from the payday and convert the difference to whole days, rounding up partial days.
Worked example
From 30 August to 1 September is 2 days until payday — useful for timing a bill payment or checking if you need to stretch the last week's budget.
Where this can give the wrong answer
- If payday is before the from date, the calculator errors — it's for forward-looking countdowns only.
- Biweekly pay needs you to pick the correct upcoming date, not a generic 'every other Friday' rule.
- Public holidays shifting deposit dates aren't adjusted — use the date funds actually hit your account.
FAQ
- It counts calendar days between dates with partial days rounded up — treat the output as an approximate countdown, not payroll policy.
