Free Online Date & Planning Tools

Sort out hours, deadlines and countdowns with free online date tools that work right in your browser, with no sign up. Total a week of shifts, skip weekends when counting a deadline, line up a call across cities or watch a countdown tick down. Nothing you type is uploaded.

Hours, pay and payroll formats

Total a week of shifts in the Time Card Calculator, then see what the extra hours are worth with the Overtime Pay Calculator. Reshape the result with the Decimal Hours Converter or the Military Time Converter before it goes anywhere near payroll, so the figures already sit in the format your timesheet asks for. The Julian Date Converter answers the odd date codes that turn up on paperwork.

Counting days without the weekend

Counting a deadline by hand is where schedules slip, because a plain day count includes Saturdays and Sundays. The Business Days Calculator skips weekends when you are counting business days between two dates, and the Week Number Lookup tells you which ISO week a date falls in, which matters when colleagues plan by week number. The Day of the Week Finder and Leap Year Checker settle the rest, and the World Clock lines up a call across cities.

Nothing leaves your device

Every calculation happens on your own phone or computer. The shift times, pay rates and birth dates you type into the Time Card Calculator or the Birthday Countdown are never sent to us, there is no account to create, no email address to hand over and nothing stored about what you checked. Close the tab and your entries are gone, which makes these safe to use on a work or shared computer, whether you are checking the Year Progress Bar or the Life Calendar.

Frequently asked questions

How do I calculate business days between two dates?

Count every calendar day in the range, subtract the weekend days, then subtract any public holidays that land on a weekday. A quick manual method is to divide the total days by seven, multiply the whole weeks by five, and hand count the leftover days at each end. A 30 day span usually works out to 20 to 22 business days. The Business Days Calculator does that counting for you and shows the working days total directly.

Is my timesheet data uploaded anywhere when I use the time card calculator?

No. The Time Card Calculator does all its adding up on your own device, so the start times, break lengths and hourly rates you enter never leave it. Nothing is uploaded, there is no sign in, and nobody on our side ever receives the form. Your entries stay on the page only until you refresh or close the tab, so you can total a week of shifts on a shared or work computer without leaving anything behind.

How do I convert hours and minutes into decimal hours for payroll?

Divide the minutes by 60 and add the result to the hours. Seven hours and 45 minutes becomes 7.75, and eight hours and 20 minutes becomes 8.33. Payroll systems expect this decimal form because an hourly rate cannot be multiplied by 7:45 directly. The Decimal Hours Converter handles the conversion in both directions, and the Military Time Converter helps when your shift log records 1800 rather than 6:00 PM.
