How it works

  1. 1

    Create the event

    Name it, pick a date range of up to 14 days, and set the daily window and how long you need. No account, no email address.

  2. 2

    Share one link

    You get a single link. Anyone who opens it can add a display name and paint their availability — there is nothing to install and nothing to sign up for.

  3. 3

    Add a ZIP board, optionally

    If where to meet is also in question, turn on the ZIP board when you create the event: pick an anchor ZIP and a radius, and each participant taps the nearby ZIP codes that work for them. The ZIP data covers Massachusetts for now.

  4. 4

    Read the overlap

    Every answer stacks onto a heatmap and a ranked list of the best windows, so the time that works for the most people is the darkest block on the wall. Events with a ZIP board get the same ranking for places.

Questions

Do I need an account to use SameWhen?
No. SameWhen has no accounts, passwords, or email sign-up. You create an event, share the link, and everyone who opens it picks a display name to paint their availability.
Is SameWhen free?
Yes. Creating events, sharing the link, and collecting availability are free, and there is no paid tier to upgrade to.
How many people can answer one event?
SameWhen is built for a group of friends or a team — roughly a couple of dozen people per event. You can optionally set an expected headcount, which becomes the denominator on the heatmap.
How does SameWhen handle time zones?
It does not convert them. Availability is stored as wall-clock time, and everyone in an event is assumed to be in the same local timezone, so nobody's grid shifts because of the device they answered on.
Can search engines find my event link?
No. Event pages are served with noindex and a no-referrer policy, and they are excluded from the sitemap and robots.txt, so they stay out of search results. The link is the access control — share it only with your group.
How long is my event data kept?
Events are deleted six months after their last date, and deleting an event removes its participants and availability with it.
Can SameWhen help pick where to meet, not just when?
Yes, on events where the host turned it on. When you create an event you can add a ZIP board with an anchor ZIP and a radius, and participants tap which nearby ZIP codes work for them alongside painting their availability. The results rank ZIPs by how many people picked each one, the same way they rank times.
How does the ZIP board work, and where does it work?
The map shows the ZIP codes within the radius you set around the event's anchor ZIP, and each participant taps the ones that work for them. It counts overlap rather than computing a midpoint — there is no travel-time estimate and no venue suggestion. The ZIP data covers Massachusetts only for now, so an event anchored outside it has nothing to show.
How is SameWhen different from a poll or a calendar invite?
A calendar invite asks people to accept a time you already chose. SameWhen collects 30-minute availability from everyone first and then shows where it overlaps, so the meeting time is a result rather than a guess.
