- Click "Copy" to put the plain-text schedule on your clipboard, or "Reset" to clear everything.
About this event timeline planner
The event timeline planner converts a start time and an ordered list of named segments into a complete run-of-show schedule. For each segment you supply a name and a duration in minutes; the tool chains them end-to-end, displaying a Start column, an End column, and the segment name. Events that run past midnight are handled automatically — any time that rolls over to the next calendar day is labelled "+1 day" in the output.
The arithmetic is additive: the tool converts the 24-hour start time to a total number of minutes from midnight, then walks forward by each segment's duration in turn. The end of one segment becomes the start of the next. Each absolute minute offset is then converted back to HH:MM, and any multiple of 1440 minutes triggers a "+1 day" (or "+N days") label. Total event duration is reported beneath the table in hours and minutes.
For example, a wedding reception starting at 18:00 with five segments — Welcome drinks (45 min), Dinner (90 min), Speeches (30 min), First dance (15 min), and Open dancing (180 min) — produces: 18:00 Welcome drinks, 18:45 Dinner, 20:15 Speeches, 20:45 First dance, 21:00 Open dancing, ending 00:00 +1 day; total duration 6h. Event planners, conference organisers, and stage managers can use this tool to draft and share a schedule in seconds.
FAQ
- What is the event timeline planner and what does it produce?
- It takes a 24-hour start time and an ordered list of named segments (each with a duration in minutes) and generates a timestamped run-of-show table showing the start and end time of every segment, the overall end time, and the total event duration.
- Does the event timeline planner support events that run past midnight?
- Yes. Any segment whose calculated time crosses midnight is shown as "+1 day" in both the on-screen table and the copied plain-text output. Events spanning more than 24 hours display "+2 days", "+3 days", and so on.
- Can I reorder segments after adding them?
- Yes. Each segment row has ↑ and ↓ arrow buttons. Moving a segment up or down immediately shifts all subsequent start and end times when you next press "Generate timeline".
- Does my plan save if I close the tab?
- Yes. The tool automatically saves your start time and all segments to your browser's localStorage on every change, so your draft is restored when you reopen the page on the same browser. Clearing site data or using private/incognito mode will wipe the saved state.
- Can I export the run of show?
- After generating the timeline, click "Copy" to place a plain-text version of the full schedule on your clipboard. You can then paste it into a document, email, or messaging app.
- Is the event timeline planner free, and does it store my data on a server?
- It is free with no account required. All calculations run in your browser; no segment names, times, or other data are transmitted to any server.
