For a room spread across countries
Pick the zone you will be presenting in, put its label beside the start time, and repeat that exact wording on the page, in the confirmation email and in every reminder. One number, everywhere.
"Seven o'clock" is the problem, not geography. A person in Lisbon and a person in Helsinki reading the same invitation with no zone label both assume it means their own evening, and only one of them turns up at the right hour. Nothing about the meeting platform is at fault; the sentence was incomplete.
A start time in a webinar needs three parts to be usable: the hour, the day, and the zone it belongs to. Give all three and the arithmetic is on the attendee for exactly one line, which is what they expect. Leave one out and you get the situation every host dreads — people arriving two hours early, politely waiting, or not arriving at all.
The test is simple: copy each line out and compare. Any difference is the one that will cause an email.
You pick one reference point and stay with it. Here is how hosts usually decide.
The safest default, because the hour on the page is the hour on your own wall and you can answer any question about it without checking anything. Most rooms with one speaker choose this.
Worth it when the majority sits somewhere else and you are willing to present at an awkward hour yourself. Whoever you choose, the label stays the same in every message.
Central European Time reads more reliably than an abbreviation, which people mishear and which can mean different things in different seasons. Write the name out and, if useful, add one anchor: the same hour in London.
All three are correct. The mistake is using one on the page and another in the email.
Thursday 12 February, 19:00 Central European Time. Runs fifty minutes.
We start at 19:00 Central European Time, which is 18:00 in Dublin and Lisbon. The session runs fifty minutes either way you write it down.
If the hour does not suit where you are, register anyway. The material goes out to the list afterwards, and the page will say when the next date is.
Be clear with yourself about one thing: the page shows the start time with the zone label you chose. It does not work out each visitor's local hour and rewrite itself for them, and it does not detect where someone is. Anyone reading it at 22:00 in Reykjavik sees the same line as anyone reading it at 22:00 in Warsaw.
That is not a limitation to apologise for; it is a reason to write the time carefully once rather than hoping a tool sorts it out later. If you want to give people a diary entry, the confirmation email carries a calendar file and a Google Calendar link, and both are built from the time stated on your page — another place where an ambiguous hour becomes an ambiguous appointment.
And if the audience is genuinely split across many hours, the honest answer is not a cleverer time format. It is two dates, which means two pages, because one page holds one session.
How it works
Write them on one line first. If that line is hard to phrase, the session will be hard to attend, and it is cheaper to fix the date now.
Both live in the session details, so the published page shows the hour and the label together rather than a bare time.
Register once with a spare address and read the email it sends. The time there should be the same sentence as the time on the page.
The automatic emails repeat the stated time. Anything you send from your own account should copy it word for word.
Questions
No. The page shows the one time you set, with the zone label you chose, for every visitor. Write the label in full and repeat it consistently, because that is what people have to work from.
One named zone plus the hour is clearest. If you want to help a big group elsewhere, add a single anchor line — the same hour in their city — rather than a table of six conversions nobody reads twice.
The confirmation email carries a calendar file and a Google Calendar link, both built from the time you entered. There is no separate add-to-calendar button for other services on the page itself.
Two pages, one per date. A single page is a single session, so the second start gets its own page, its own seat limit and its own registrant list — which is also useful afterwards, since you can follow up with each group separately.
Get Started
Choose the zone you will present in, write it out beside the hour, and copy that exact sentence onto the page, into the emails and into every post. Confusion about the time is almost always a wording problem.
