Frequently Asked Questions
How do I enter a week?
One row per day, each with a start time, an end time and an optional unpaid break. Every row shows its own worked duration and the totals update as you type. Rows can be labelled with a day, a date or a client.
Does it handle night shifts?
Yes. When the end time is earlier than the start, the shift is treated as crossing midnight, so 22:00 to 06:00 with a 30-minute break is 7.5 hours — not a negative number.
Why do the decimal hours come out exactly?
Because every row is accumulated in whole seconds and converted to decimal hours only at the end. Adding decimal hours as you go drifts — a week summed in tenths of an hour lands on 39.99999999999999 — and a payroll figure that is a cent out is a real problem for the person being paid.
Can it work out what I am owed?
Yes. Supply an hourly rate for a gross figure, with an optional overtime threshold and multiplier. Forty hours at $50 reports exactly $2,000. Money is rounded to cents once, at the end, rather than at each row.
Are my hours stored anywhere?
No. There is no account, no server and no saved timesheet — everything is calculated in your browser and disappears when you close the tab. Analytics receives only the number of rows and whether a rate was used, never your times, labels or earnings.
