Online advent calendar maker
Create a calendar of little surprises and send it as a link. No account or email needed.
Messages behind the doors
Preview: all doors can be opened here. Recipients will see the date lock.
Tap a numbered door. Each day becomes available at local midnight on your device.
The calendar is inside the link, not saved by this tool. Anyone with the link can read all messages. It is not encrypted. Opened doors reset on refresh. The site’s usual privacy and advertising controls still apply.
How to make a virtual advent calendar
Give your calendar a title, add who it is from and choose a colour theme. Pick 24 doors for the countdown to Christmas Eve, 25 through Christmas Day or 31 through New Year’s Eve when starting on 1 December. You can also choose another start date for a different occasion.
Write a short message behind each door, with an optional emoji or website link. Choose a numbered or shuffled layout, then preview the calendar before sending it. Preview lets you check every surprise, including future days. Return to the editor to make changes and copy the finished link into your usual messenger.
Ideas for personal messages
Mix warm wishes with tiny activities: share a happy memory, invite someone for a walk or suggest drawing a funny snowman. The three collections offer 31 wishes, acts of kindness or activities for children. Fill with ideas only completes empty messages, so your own notes stay in place. Adapt activities to the recipient’s age and interests.
How the link works without a calendar server
The tool packs the calendar into the part of the address after #. It uses compression when the browser supports it, or an uncompressed format otherwise. That fragment is not part of the page request sent to the server. Keep the entire link: shortening or cutting it can lose the calendar. The full address may contain at most 8000 characters.
Frequently asked questions
Do I need an account or email address?
No. Creating and receiving a calendar requires neither. The calendar itself stays in the link; the tool does not upload it or create a server record.
Can someone open future doors early?
Yes, a determined person can bypass the browser’s date check or read the link data. This is a playful surprise, not a security feature or encryption. Do not include confidential information.
Which time zone opens a door?
Each door becomes available on its date in the recipient’s local time. Day one is the start date, day two is the next calendar day, even across month boundaries.
Are opened doors remembered?
Only while this page stays open. Refreshing closes them again, but any day whose date has arrived can immediately be reopened. No local storage is used for the calendar.
Can I print the messages?
Yes. Use the editor’s print button for a dated list of every message, intended for a parent or organiser. Check the print preview before printing or saving a PDF.
Can I change a link I already sent?
No. Each link contains its own version. Edit the calendar while the editor is open and send a new link. Keep a copy before closing; there is no account recovery.
Can I add music or videos?
Add an http or https link. Recipients see its address and choose whether to open it in a new tab. Videos and other sites are never embedded in the calendar.
