World Down Syndrome Day 2038 Countdown

When is World Down Syndrome Day 2038?

World Down Syndrome Day 2038 is counted down to Sunday, March 21, 2038 at 12:00 AM UTC. The canonical URL keeps the year in the path, so World Down Syndrome Day 2038 and World Down Syndrome Day 2039 are separate target-date pages.

Plan across time zones

• World Down Syndrome Day is fixed on March 21.
• Publish local event times, venue details, and campaign cutoffs separately from the public date.
• Use UTC as the canonical event timezone for this countdown.
