A little door to open every day.
Hidden Days turns the advent-calendar ritual into a gift for any occasion. Hide photos, notes, and videos behind numbered doors that unlock one day at a time — then send it to someone you love with a single link.

Half the gift is the waiting.
Any occasion, not just December
The advent-calendar ritual, freed from the season. Eight occasion templates — from birthdays and weddings to gratitude, habits, and custom countdowns — set up the doors, dates, and prompts for you.
Doors that unlock one day at a time
Each numbered door opens on its scheduled date. Locked doors politely refuse an early peek, today’s door gently pulses, and every reveal lands with a satisfying flip.
Real surprises inside
Fill doors with photos, voice notes, written messages, and QR-code links. Pro adds video doors — and even a gift card the recipient claims with a tap on the big day.
Share with a single link
Recipients open your calendar in any browser — no account, no install, nothing to set up. Hearts and replies on every door come straight back to you.
Every detail, yours
Warm, handmade-feeling calendars out of the box. Pro adds custom covers and themes, a background soundtrack, your own share link, scheduled delivery, and viewer analytics.
Private by design
Only people with your link can see a calendar, and Pro adds a password for an extra lock. Future doors stay sealed on our servers until their day — no ads, and your data is never sold.
Cards get opened once and set down. Hidden Days brings people back every morning.
Start with one calendar, free
Free covers a calendar with up to twelve doors. Hidden Days Pro unlocks unlimited calendars, video doors, and every finishing touch — as a subscription, or a one-time unlock for a single calendar.
