Invitations and attendance communication
Announcing a change of event date
The date has to move, people have already blocked their diaries, and the message needs to say what happens to their registration.

The short answer
A date-change announcement states the new date first, then what it means for the reader's registration and what they must do. Before you write it, settle the venue, speaker and supplier position for the new date and decide how you will treat people who cannot attend it.
If the answer to a question is not yet known, say so and give the date by which you will confirm it.
Settle these before announcing
- Is the new date confirmed in writing by the venue and the key speakers or suppliers, or only provisional?
- Does every existing registration carry over to the new date automatically, or must people re-confirm?
- What is the position for people who cannot attend the new date? Terms, fees and refunds are questions for your signatory and, where relevant, a legal adviser, not for the announcement author.
- Which other messages, reminders and deadlines in your invitation sequence move with the date?
- Who approves the wording, and which audiences hear first?
What changes for each audience
| Audience | Typical effect | What the message needs |
|---|---|---|
| Registered delegates | Diary and travel plans change. | New date, whether registration carries over, how to say they cannot attend. |
| Speakers | Availability must be re-checked. | New date and a request to confirm by a set date. |
| Sponsors and exhibitors | Schedules and materials move. | New date, revised contacts for logistics. |
| Waiting list | Their position may change. | Short factual note on what happens to the list. |
| Suppliers and venue | Bookings and holds move. | Written confirmation of the new date and any changed terms. |
Wording that works
Lead with: The date of [event] has changed to [new date]. Then say whether registrations carry over, what the reader must do, and by when.
Give the reason in one factual sentence only if you are free to share it. Say what stays the same, such as the venue and programme, only if that is true.
After sending
- Update the website, calendar invitations, registration confirmations, badges and supplier briefs.
- Track replies from speakers and sponsors, and escalate anyone who has not answered by the date you set.
- Record those who cannot attend the new date and handle them under the terms your signatory confirms.
- Send revised reminders and joining instructions on the new schedule.
Worked example · Fictional example
A forum moved by two weeks
Fictional organisation and figures, for illustration only.
A fictional logistics association moves its half-day forum by two weeks after its venue offers a different slot. The committee confirms the venue and the three main speakers in writing, then announces the new date to 150 registered delegates.
Registrations carry over automatically. Delegates who cannot attend are asked to reply to the secretariat by a set date, and the secretariat logs each case for the signatory to decide under the registration terms.
Use this yourself
Date-change announcement template and action log
Fill in the brackets after the new date is confirmed in writing. Copy the log columns into a shared sheet.
- Subject: New date for [event]: now [new date]
- Opening: The date of [event] has changed from [old date] to [new date]. [Venue and times unchanged / changed as follows].
- Your registration: [carries over automatically / please confirm by date].
- If you cannot attend the new date: please tell [role] by [date] and we will [the process your signatory confirms].
- Reason (only if free to share): [one factual sentence].
- What stays the same: [programme, venue, fee].
- Next message: revised joining instructions by [date].
- Log columns: audience, name, informed on, response, can attend yes/no, action owner.
- Question for signatory: what applies to people who cannot attend the new date?
Handle it in-house, or bring in help?
Your team can usually handle this when
- The new date is confirmed and affects one venue and a short list of speakers.
- Registrations carry over with no exceptions.
- One person approves wording and handles replies.
Outside planning help earns its fee when
- Many speakers, sponsors and suppliers must all re-confirm for the new date.
- Registration terms or cancellation questions need careful handling.
- Messages, reminders and deadlines across several lists all need moving at once.
Need the change run as one coordinated move?
A conference project lead can confirm the new date with the venue, speakers and suppliers, sequence the announcements, track who has re-confirmed and keep your reminder schedule aligned. Registration terms and refund questions stay with your signatory. Send the old date, the proposed new date and your current confirmations.
Questions organisers ask
Should we announce a provisional new date?
Only if people need to hold diaries, and say plainly that it is provisional and when you will confirm it.
Do registrations transfer automatically?
That is your decision, and your registration terms may affect it. Say which you have chosen in the first paragraph.
How do we handle people who cannot attend the new date?
Collect their replies by a set date and record each case. Ask your signatory or legal adviser what the registration terms allow before replying.
