Valentine's Day is also a day to thank a friend. In Finland and Estonia, February 14 is officially Friend's Day. On Lettie, sending one letter between Feb 8, 12:00 UTC and Feb 15, 12:00 UTC earns a free Valentine's stamp (a white heart on pink).

Not every country or family celebrates Valentine's Day. Ask first: "What do you do on February 14?"

Three lines for a friend

  1. One moment you were grateful for — "the letter you sent last month when exams were wearing me down".
  2. One thing you like about them — "you always leave me a question, so writing back is fun".
  3. One thing to do together — "let's each send a photo of our neighbourhood this year".

Example letter

Happy Friendship Day! In Finland today is Friend's Day, so I wanted to write to you. I still reread the letter you sent last month when I told you exams were wearing me down. You always leave me a question, which makes writing back a joy. Shall we swap a photo of our neighbourhoods this year?

A few cautions

  • With a pen pal you just met, skip lines that read like a love letter. Translation can make them sound stronger. "Thank you" and "I love your letters" are plenty.
  • Don't expect anything back. A letter is a gift, not a trade.
  • White Day (March 14) has a holiday stamp too. The reminder goes to people in KR, JP, TW, CN.

The holidays around Valentine's are Lunar New Year and Cat Day. The full schedule is in the holiday stamp calendar; for thank-you letters, see Thanksgiving letter to a friend.
