How Many Days Until Mother's Day 2028?

Mother's Day 2028 is Sunday, 14 May 2028

There are 625 days between 28 August 2026 and Mother's Day 2028, which falls on Sunday, 14 May 2028. That is 89 weeks and 2 days, or 426 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 2028-05-14 in ISO form and 5/14/2028 in the US format, it falls in ISO week 19 of 2028, and it is day 135 of 366.

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 2028 that is 14 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.

Every convention used above — whether the start date counts, how month ends are clamped, which holidays close an office — is written out on the methodology page, including how we count the 426 working days above.
