A digital time capsule, built of letters

How it works

Three steps, and no magic beyond what time does on its own:

• Write the letter like any other: stationery, seal, your own pace.
• Choose the time-capsule ritual and a delivery date — a specific day, not “someday”.
• The letter waits encrypted. Nobody — including us — can read it until it comes back to you on the day you chose.

What people write into a capsule

A time capsule needs no grand occasion, but a few moments suit it especially well:

• New Year’s Eve or a birthday — a letter to reckon with, one year out.
• The eve of a big change: a move, a new job, a wedding.
• A letter to your future self — the honest kind, since there is nobody to pose for.
• An anniversary letter — to yourself, or to the two of you.

Why it beats memory

Memory smooths things over. Years later we keep the conclusions and lose the ordinary days — and the ordinary days are what is worth rereading. A letter freezes the day as it was: the prices, the sounds, the worries that felt enormous.

Unlike a notes app, a scheduled letter cannot be peeked at early and cannot be quietly rewritten. It arrives — sealed, dated, and exactly as you left it.
