HOW TO USE IT
Choose a date, then leave room for change
Pick a writing date and a later opening date. The countdown uses calendar dates rather than hours, so changing clocks does not alter the number of days. A meaningful date can be a season change, an anniversary or an ordinary day you choose.
Start with a concrete detail that might otherwise disappear. Ask one open question and add a kind reminder. Download or print the card before leaving. You can put the physical card somewhere safe or use a letter app if you want app-based future-letter features.
A WORKED EXAMPLE

This browser worksheet does not save, lock, deliver or remind you to open the letter.
