Ramadan 2029 is Tuesday, 16 January 2029
There are 881 days between 19 August 2026 and Ramadan 2029, which falls on Tuesday, 16 January 2029. That is 125 weeks and 6 days, or 600 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 2029-01-16 in ISO form and 1/16/2029 in the US format, it falls in ISO week 3 of 2029, and it is day 16 of 365.
How the date of Ramadan is decided
Begins with the sighting of the crescent moon marking the first day of the ninth month of the Islamic calendar. Because the Islamic year is purely lunar it moves about eleven days earlier each Gregorian year, and because the start depends on local moon sighting, the date can differ by a day between countries. Any date given in advance is an estimate.
That makes it a computed date: there is no fixed day and no simple weekday rule, so it has to be worked out from a formula or a calendar of its own each year. In 2029 it works out as Tuesday 16 January.
This date is an estimate, not a fixed point. Ramadan depends on observation rather than arithmetic, so the date announced locally can differ by a day from any date calculated in advance, and it can differ between countries in the same year. We show the arithmetic approximation and label it, rather than presenting it as settled. If the date matters — for travel, a booking or time off — confirm it with the community or authority you are following. How we produce these dates, and which of them are approximate, is set out on the holiday sources page.
Ramadan 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.

Both the date and the weekday move, because the rule is not tied to either.
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 600 working days above.
