How it works
-
Pick "one day" or "week"
In "one day" mode you fill in a single shift. In "week" mode you can add up to 7 days — the "+ add day" button creates a new row and each day can be removed.
-
Fill in the times
Clock in, lunch out, lunch back and clock out. No lunch break? Leave the two middle fields empty. If a time does not add up, the tool tells you what to check.
-
Read the total (and the pay, if you like)
The total worked appears instantly, in h:mm. Filled in the "Hourly rate (optional)" field? You also see what you earned today or the week pay.
Frequently asked questions
Does it calculate overtime?
It does not split overtime out — it shows the total worked, and the comparison is up to you: 9:30 on an 8:00 shift means 1:30 extra. Note the hourly rate is applied flat to every hour, with no overtime premium — that part you do separately.
Do I have to fill in the lunch break?
No. Skipped the break? Leave "Lunch out" and "Lunch back" empty and the total runs straight from clock-in to clock-out. Just do not fill one and forget the other — the tool will ask you to complete it.
How do I add up a whole week?
Click "week", fill in each day and use "+ add day" as far as you need (7 days max). Each day shows its own total, and below comes the week total — with the week pay, if you entered an hourly rate.
I work nights and clock out the next day. Does it work?
Not yet — times must fit inside the same day, so a clock-out before the clock-in makes the tool ask you to check. Workaround: split the shift across two days in week mode (clock-in to 23:59 on one, 00:00 to clock-out on the other).
How do I find my hourly rate?
A common rule for monthly salaries: divide the monthly pay by your contracted monthly hours. A $2,200 salary over 220 hours is $10 an hour. Comma or dot as decimal separator, either works.
Are my times and salary sent anywhere?
No. The math happens in your browser, on your device — nothing goes to any server. You can even turn off Wi-Fi after the page loads.
