Event Schedule Maker

Build a free event schedule by entering a start time and the duration of each segment. Change a duration and all following times recalculate automatically, so you can adjust when an event runs over or finishes early. Use it for parties, weddings, presentations, and company events.

Edit the event name, start time, or durations to refresh the schedule. Choose a preset to get started.

How to use

1. Set the start time

Enter a start time under “Event details.” Add a target end time to see whether the schedule fits. The summary shows how many minutes over or under the target it is.

2. Add segments and durations

Enter each segment name and duration. Times are calculated automatically. Durations are limited to 0–600 minutes; negative values become 0, decimals are rounded down, and values over 600 become 600. You can add up to 40 segments, reorder them with the arrow buttons, or remove them with ✕.

3. Later times recalculate automatically

This is the key feature. When you change a segment’s duration, all following times recalculate automatically. See how a five-minute delay changes the end time without using a calculator.

4. If the event starts late

Select “Set start time to now” to shift the entire schedule to the current time if the event starts late.

5. Share or print

Select “Copy share link” to make a URL that opens the current schedule. Keep the URL shown below the button, then send it to staff or co-organizers. Embedded browsers may block saving or copying, so open the displayed URL in a regular browser tab. “Print schedule” prints the schedule as a run sheet, and “Copy schedule as text” prepares it for chat or email.

About saving

“Save” stores the schedule in this browser only. It is not sent to a server and cannot be loaded from another device or browser. Saving and sharing are separate; use the share link to access the schedule on another device.

Frequently asked questions

Can I use a preset as-is?

Yes. Customize the party, wedding, or presentation preset with your event name and activities. Add or remove segments to match your plan.

How do I adjust the schedule when an event runs over?

Change the duration of the segment that ran over. All following start and end times recalculate automatically. Set a target end time to check whether you are now over or under.

Can I share the schedule with staff or another device?

Yes. Send the link created with “Copy share link” so others can open the same schedule. “Save” only stores it in the current browser.
