How Many Days Until Mother's Day 2029?

Mother's Day 2029 is Sunday, 13 May 2029

There are 989 days between 28 August 2026 and Mother's Day 2029, which falls on Sunday, 13 May 2029. That is 141 weeks and 2 days, or 675 working days once Saturdays, Sundays and the US federal holidays in between are taken out — the figure that matters if you are counting delivery lead time or a work schedule rather than sleeps. The date is 2029-05-13 in ISO form and 5/13/2029 in the US format, it falls in ISO week 19 of 2029, and it is day 133 of 365.

How the date of Mother's Day is decided

The second Sunday in May in the United States, so it falls between 8 and 14 May. Other countries use different dates entirely — the United Kingdom's Mothering Sunday is in March.

That makes it a floating date: it is pinned to a weekday rather than to a day number, so it is always a Sunday but the date moves. In 2029 that is 13 May.

Mother's Day is an observance rather than a federal holiday. Offices, banks and schools stay open unless an individual employer chooses otherwise, and it counts as an ordinary business day in every calculator here. Only the eleven federal holidays are treated as non-working days — the list and the reasoning are on the holiday sources page.
