Group common time finder
Find overlapping availability without sharing a calendar account. Use one time zone and one day for everyone, and enter separate rows for separate time windows.
Your inputs
Start with the example values, then replace them with your own. For tables, keep the vertical bar separators and use a dot for decimals.
Confirm availability with participants. All entered times must use the same date and time zone; this tool does not send invitations.
Tool inputs are processed in your browser and are not submitted by this tool. Existing site analytics and advertising services have their own privacy terms.

How it works
For a single day and shared time zone, merge each person’s availability, then intersect all participants’ intervals.
Worked example
These sample results use the original example inputs in the form. They do not change when you edit your inputs; your own result appears in the workspace.
- Common time: 120 minutes
| Start | End | Minutes |
|---|---|---|
| 19:00 | 21:00 | 120 |
Read the result carefully
Results depend on the values and assumptions shown above. Change one input at a time to see its effect. A blank or unavailable result means the data does not support a calculation; it is not zero.
