A calendar the whole group fills in

Instead of comparing separate personal calendars, everyone marks their availability directly onto one shared grid. As responses come in, each date shades in a deeper colour the more people are free that day, so the strongest date stands out visually, no counting required.

Colour-coded heatmap

Darker shading means more of the group is free on that date. Scan the row and the best date jumps out immediately.

As broad or as precise as your group needs

A single availability calendar adapts to how far out and how precisely you need to plan.

Month-by-month view

Flip between months to compare availability across a longer window instead of squinting at a single week.

Multi-week ranges

Set a date range that spans several weeks and the calendar lays every date out on the same shared grid.

Time-of-day granularity

Choose whole days, half days, or specific hour slots so the calendar matches how precisely your group needs to plan.

How it works

  1. 1

    Create your shared calendar

  2. 2

    Share the link with the group

    Drop it into WhatsApp, Slack, email, or wherever the group talks. No account needed to open it.

  3. 3

    Twenty seconds per person, on the same shared calendar grid, from any phone or laptop.

  4. 4

    Confirm the date that lights up brightest

    Lock it in, then send everyone a Google Calendar link or an .ics file so it lands straight in their own calendar.

Shared calendar vs. group chat

"What dates work for everyone?" is a question a group chat is bad at answering. A shared availability calendar is built for exactly this.

Group chat or spreadsheet

Replies scattered across dozens of messages, half the group never answers, and someone has to manually tally who said what against a calendar in their head.

Shared availability calendar

Every response lands on one grid automatically. The best-covered date is visible at a glance, no tallying, no scrolling back through messages.

Calendar invite ping-pong

Sending one proposed date at a time and waiting for declines means days of back-and-forth before you even find out who's actually free.

One link, one calendar

Everyone answers once, on their own time, against the same full date range, instead of one round-trip invite at a time.

Works with the calendar you already use

The shared calendar is where the group agrees on a date. Once it's confirmed, getting it into your own calendar takes one tap.

Add to Google Calendar

Once the organiser confirms the date, a one-click Google Calendar link is available on the event page.

Download an .ics file

Prefer Apple Calendar, Outlook, or something else? Download the confirmed date as a standard .ics file and import it anywhere.

Built for every kind of group

The same shared calendar works whether you're coordinating a work team, a poll of loose date options, or a specific kind of get-together.

Group availability tool

A broader look at coordinating any group's availability in one place.

Group availability poll

Prefer a simple vote on a shortlist of dates instead of a full calendar view? Try the poll format.

Work meetings

Find a slot your whole team can make for a recurring or one-off meeting.

Group holiday

Line up the dates everyone can take off for a trip away.

Christmas party

Pick the date for the work Christmas party before everyone's December fills up.

Calendar and availability guides

Frequently asked questions

What is a group availability calendar?
A group availability calendar is a single shared calendar view where every member of a group marks the dates (and optionally times) they're free. Instead of comparing individual calendars or reading a group chat, everyone's availability is layered onto one grid so the best date is visible at a glance.
How is this different from just sharing a Google Calendar?
Sharing a personal calendar shows your own busy/free blocks, not the group's overlap. A group availability calendar is built the other way round: it's one blank grid that the whole group fills in together, purpose-built to answer 'which date works for everyone' rather than 'what's on my calendar.'
Do people need an account to mark their availability?
No. You share a link, and anyone with the link can open the calendar and tap the dates they're free. No sign-up, no app download, no account required for responders.
How does the calendar show the best date?
Each date on the calendar is colour-shaded based on how many people are free that day, a darker or bolder shade means stronger coverage. The calendar also highlights the single best date and the best day of the week, so you don't have to count responses by hand.
Can the calendar show times as well as dates?
Yes. You can choose the granularity when you create the calendar, whole days, half days (morning/afternoon/evening), or specific hour slots, so the shared view can be as broad or as precise as your group needs.
Can we view more than one month at once?
Yes, the calendar supports multi-week and month-by-month views so you can compare availability across a longer date range instead of being stuck looking at a single week.
What happens once we pick a date?
The organiser confirms the winning date on the calendar, and the event page then offers a Google Calendar link and a downloadable .ics file so everyone can add the confirmed date straight into whatever calendar app they already use.
Is a group availability calendar free to use?
Yes. The free plan includes one active 30-day availability calendar for up to five participants, and responders do not need to sign up. Pro removes the participant and active-event limits for larger or recurring groups.
What size groups does this work for?
Any size, from a handful of friends picking a dinner date to larger teams or clubs coordinating a recurring meeting. The heatmap view scales well because you're reading colour intensity rather than counting names.
