Date & Time Toolkit
Format dates, calculate durations and compare times instantly.
How to use the date and time toolkit
- Set a start date and time in the first field and an end date and time in the second.
- Use the Now button to fill both fields with the current local time.
- Read the difference in days, workdays, hours, and minutes below the fields.
- Clear the fields to start a new comparison at any time.
- Interpret the minus sign as a past interval when the end time is earlier than the start time.
When it helps
- Count the days between two project milestones or deadlines.
- Estimate working time between two dates while excluding weekends.
- Plan event durations in days, hours, and minutes.
- Check the total minutes between two timestamps for billing or logging.
- Measuring how long a support ticket or task has been open.
Frequently asked questions
Is my input processed locally?
Yes. Dates never leave your browser and no data is sent to a server. The tool only reads the values you enter.
What are the limitations?
The toolkit works with valid date and time values, so the fields must contain proper entries. Business-day counting follows a Monday-to-Friday week and does not account for public holidays.
Does it count working days?
Yes. Alongside calendar days, the result shows workdays between the two dates using a Monday-to-Friday schedule.
Which units does the result include?
The difference is broken down into days, hours, and minutes, and the total number of minutes is also shown.
Can I insert the current time quickly?
Yes. The Now button fills both fields with the current local date and time so you can measure an interval from this moment.
Does it work across time zones?
The toolkit compares the local date and time values you enter, so both fields use the same time zone on your device. It does not convert between zones or handle daylight saving transitions. For a single person working in one zone, the result is reliable.
