Distance
Long-distance countdown gift ideas aimed at the day you are together
Pick the reunion, not the anniversary, if the reunion is sooner
If you will be in the same city in sixteen days, that is a better target than a symbolic date two months away. The last door should open on the day you land, or the day they do. Say which airport in the note, not in the title, if you want the early days to stay a surprise.
What the early days are for
Early days are evidence: your desk, their street in a photo they sent, a meal you cooked badly on a call. Middle days can be a plan for the visit, still vague. The last two days can be specific. Because the timezone is theirs, you will often be asleep when a door opens. That is fine. Write it that way.
Preview is free. The link is the purchase.
You can fill the days and read them yourself before paying. They only get the link after you publish. One payment, $9.99, publishes one countdown. If you are making one for each of you, that is two gifts.
