For offices & people teams
The workplace advent calendar: a daily ritual your team will actually keep

An advent calendar for the office is one of those ideas that sounds like a nice-to-have and turns out to be load-bearing. A daily door gives December a rhythm: something small to look forward to, something to mention in stand-up, a reason the quiet weeks before the holidays feel like a shared season instead of a slog. It's the rare engagement idea that costs little, excludes no one, and repeats twenty-four times.
Here's how to run one — the DIY versions, what to put behind the doors, and the hosted option that turns the calendar itself into a game.
DIY office advent calendar ideas
If you're building your own, these formats work in real offices:
- The treat wall — 24 numbered envelopes or boxes by the kitchen; a different person opens each day's on behalf of everyone
- Rotating gifter — each team member owns one door and fills it (cap the spend at £5); half the fun is guessing who chose what
- The activity calendar — each door is a micro-event: mince pies at 3pm, jumper day, a two-minute quiz in stand-up, early finish Friday
- The kindness calendar — each door is a small prompt (thank someone specific, buy the next coffee); low cost, surprisingly sticky
- Digital DIY — a daily post in a dedicated Slack channel; free, but it lives or dies on one person remembering every morning
What to put behind the doors
Good door contents alternate between treat, moment, and prompt. Treats are the sweets and scratch cards. Moments are the shared ones — the quiz, the playlist add, the 3pm gather. Prompts get people interacting: today's question in the channel, vote for tomorrow's biscuits. All-treats calendars fizzle by day ten; the mix is what keeps people opening.
The consistent failure mode of DIY calendars is the same as DIY anything: they depend on one enthusiastic person, and that person has an actual job. Miss two days in week two and the ritual quietly dies. Which is the case for the hosted version —
The hosted version: an advent calendar that's also a game
Doorly for Teams is a workplace advent calendar that runs itself — and instead of sweets, the doors contain a story. Over 24 days your team plays Murder at Mistletoe Manor: each door reveals a clue, a suspect, or a twist, everyone theorises together in Slack or Teams, and the colleague who cracks the case is revealed as the winner on Christmas Eve.
Everything the DIY versions struggle with is handled: doors unlock automatically every morning, remote and hybrid people get the identical experience on any device, nothing needs restocking or remembering, and there's a comms kit with ready-made channel posts if you want to stoke the conversation. Setup is one link shared once.
It also gives the calendar something DIY can't: a narrative arc. A sweet a day is pleasant; a mystery a day is a conversation. By week two you'll have suspects with fan clubs.
Office vs. remote vs. hybrid
Physical calendars suit single-office teams and die on contact with remote work — half your company can't open an envelope in a kitchen they've never visited. If your team is remote or hybrid, the calendar needs to be digital and asynchronous by design: same door, same day, every location and time zone. That's the gap the hosted format was built for, and why distributed companies are its heaviest users.
Cost and setup
DIY calendars run £50–£200 in treats plus a real number of organiser-hours. Doorly for Teams is one flat per-team price — hosted, managed, with engagement analytics, and with company branding plus the full comms kit on the larger tier. Setup takes minutes in November; from 1 December it runs itself while you take the credit.
