Conferences are not hard because any one task is hard. They are hard because thirty tasks have to happen in an order, and four of them have deadlines that are set by other people — the venue, the speakers, the printer and the visa office.

This is the timeline that keeps the other twenty-six calm.

12 to 10 months out: decide what this event is

Purpose, audience and the number you will be judged on. "Five hundred attendees" and "sixty qualified leads for sponsors" are different events.
A first budget, with the three numbers that move everything: venue, catering and expected ticket revenue. Our guide to building an event budget covers the shape of it.
Dates. Check them against the two or three events your audience also attends.

10 to 8 months: venue and platform

Shortlist and visit venues. The fifteen questions to ask before signing are worth an hour.
Choose your event platform now, not later. Registration, the call for papers and the website all sit on it.
Sponsorship packages drafted, so you can sell into a real prospectus rather than a promise.

8 to 6 months: open the call for papers

Call for papers opens, with a hard close date. Six to eight weeks is enough; longer just moves the submissions to the last week anyway. See running a call for papers.
Event website live, even if thin: a page that exists collects search traffic while you build the rest.
Sponsorship outreach begins in earnest.

6 to 4 months: registration opens

Registration opens with early bird pricing. Early bird campaigns work on a deadline, not a discount.
Reviews of submissions complete; acceptances and rejections sent within a week of each other, not trickling out.
First email campaign to last year's list.

4 to 2 months: the programme becomes real

Agenda published, clashes resolved. See building an agenda without clashes.
Speaker briefings out, with call times, room, format and what you need from them.
Catering numbers, AV requirements and accessibility provisions confirmed.
Visa letters for international attendees. This is the deadline you cannot compress.

8 to 2 weeks: the operational pass

Badge design finalised and test-printed on the real stock. Not a PDF on a screen.
Check-in plan: desks, devices, staff, and what happens when the network is down. See getting 500 people in under 30 minutes.
Final numbers to the venue; rooming lists; signage.
Reminder emails scheduled, not sent by hand on the day.

The week after: close it properly

Thank-you email with the recordings and the feedback form while it is still fresh — response rates halve after seventy-two hours.
Sponsor reports out within ten working days. Proving sponsor ROI is easier when the data was collected on the day.
The post-event report, written while you still remember why decisions were made. Here is a structure that gets read.

Keep the timeline where the work is

A timeline in a document drifts from the event within a fortnight. Keeping the dates on the same platform that holds the registrations and the agenda means the deadline moves when the event does. If you want to see how that looks in practice, start a free event on Gathervo and put this checklist into it.
