How it works
Write
Write 24 little messages, or start from our ideas for partners, friends, kids, family or colleagues and make them yours.
Send one link
The whole calendar is packed into the link. Send it by WhatsApp, text or email, or tuck it into a card.
A door a day
Door 1 opens on 1 December and the front door on Christmas Eve, in their time zone. Doors open in order, so nothing gets skipped.
Questions
What is a digital advent calendar?
A digital advent calendar is a web page with 24 doors, one for each day from 1 to 24 December. Each door hides a small surprise, such as a note, a joke, a coupon or a link, and opens on its day. Little Doors lets you write one for someone and send it as a single link.
How do I make a digital advent calendar for free?
Choose who it is for, add their name, and fill the 24 doors with your own messages or our ideas. Then create your link and send it by WhatsApp, text or email. It takes about five minutes, costs nothing and needs no account.
Does the person need an app or an account?
No. The calendar opens in any web browser on a phone, tablet or computer. They tap the link and open one door each day.
Who makes Little Doors?
Little Doors is an independent side project by Rakesh Menon, a software developer. It launched in October 2026 and is free, with no ads and no accounts.
Is it really free?
Yes. No account, no payment, no ads. It is a small side project. With your permission we count visits with Google Analytics to see how it is used.
Where are my messages stored?
Your calendar is encrypted in your browser before it is saved, and the key exists only in the link you send, after the # sign, which browsers never send to a server. So we store it, but we cannot read it. Only the names, if you choose to show them in the link preview, are stored readable. Calendars are deleted 60 days after the last door. Google Analytics, if you allow it, never receives your messages or names.
Can they peek at future doors?
Not by clicking. Each door stays shut until its day, and doors open in order, one after the other. A determined techie with the link could still read ahead, so keep big secrets for the real present.
Can I change it after sending?
Yes. Open Little Doors again on the device where you made it, or use your private edit link, change anything and press Save changes. The link you sent stays the same and shows the new version.
Can I add photos?
You can add a link on each door, for example to a shared photo album, a song, a video or a voucher. Photos themselves cannot go inside the link.
It is already December. Is it too late?
Not at all. Doors whose day has passed can be opened straight away, one after the other, so they can catch up and then get one door a day.
