Free · for D&D and any tabletop campaign
dmcal is session scheduling for tabletop campaigns. Players mark when they're free once; the DM sees the nights that work, schedules the session, and everyone answers from the email with one tap.
DMs and players sign in with Google. Players who never sign in can still RSVP from their email.
How it works
Weekly hours, every-other-week or "first and third" cadences, and one-off overrides. Players set it once; dmcal expands it across the coming weeks in each player's own time zone.
A heatmap of the whole table's free time, recommended slots ranked by who can make it, and a quorum line so "we play with four" is a rule, not a hope.
One session or a whole run of them. Each player gets an email with Going / Maybe / Can't buttons and a calendar invite; the DM hears about every answer; reminders go out the day before with last session's recap.
What's in the notebook
Every 30-minute slot across the look-ahead window, shaded by how many seats are free.
Ranked by who can make it, the campaign's usual start hour, and whether quorum is met.
Set the minimum seats you play with; the heatmap, the recommendations and the DM's emails all reflect it.
Pick up to six dates from one view and send one combined email with per-session RSVP buttons.
Going / Maybe / Can't straight from the email, no sign-in, even for players the DM added by hand.
The day before, everyone gets the time, their standing answer, and an excerpt of the DM's notes from last session.
Every session email carries an .ics invite and an Add-to-Google-Calendar button; moves and cancellations update it.
Enter a player's hours yourself until they sign in; when they do, they claim their seat and everything carries over.
Every session keeps the DM's recap and the party's notes in Markdown; the next reminder quotes last time's recap so nobody arrives cold, and a "Previously…" box covers the first dmcal session of an existing campaign.
Maps, handouts and PDFs on the campaign or on a single session, stored with the campaign and open to the whole party. Active quests sit alongside them and flow into every session email.
A player in more than one dmcal campaign never gets double-booked: sessions from the others show as conflicts on the recommendations.
Every week, every other week, or "first and third Tuesdays". Recommendations skip the gap after a scheduled session so the next suggestion lands on the right week.
Who's coming
RSVPs and party seats at a glance, quorum status, attendance, notes and docs — and for the DM, per-player delivery status of every email with a resend button for anyone it didn't reach.
In the inbox
Branded, readable on a phone, with the three answer buttons, the calendar invite, active quests, and a nudge for players who haven't claimed their seat yet.
