Last day to mail a Mother's Day card
Mother's Day moves every year — it's the second Sunday of May — so the mailing deadline moves with it. Here's the exact last day to send so her card arrives in time.
Mail by — 2027
Monday, May 3, 2027
So it arrives safely before Mother's Day on Sunday, May 9, 2027. Cutting it close? Wednesday, May 5, 2027is the latest we'd risk. That's 301 days from today.
Planning ahead? For 2028, mail by Monday, May 8, 2028 (Mother's Day is Sunday, May 14, 2028).
How we got that date
First-class mail typically takes 3–5 business days, and weekends don't count. We work back 5 business days from Mother's Day so the card lands a day or two early — early reads as thoughtful, late reads as forgotten. Around the holidays, mail volume runs heavy, so the buffer matters more than usual.
Timing and message tips
Mother's Day falls on a Sunday, and mail doesn't move on Sundays — count backward from the Friday before, not the day itself.
Early May is a heavy card week; mailing a full week ahead is the difference between relaxed and white-knuckled.
If she saves cards (most moms do), write on the inside-left panel too — she'll reread it for years.
Sending to several moms — yours, a grandmother, the mother of your kids? Address them all in one sitting so none slips.
