August 21, 2027 falls on a Saturday
August 21, 2027 is a Saturday. It is 332 days from today, September 23, 2026. The date is day 233 of 365 in 2027, it sits in ISO week 33, and it is the 21st of a 31-day month with 10 days after it.
What day of the week is August 21?
In 2027 it is a Saturday. The weekday is not a property of the date itself, it is a property of the date in a given year, so the honest answer always names the year. A common year is 365 days, which is 52 weeks plus one spare day, so a fixed date moves forward one weekday from one year to the next. A leap year inserts a second spare day, so the step is two whenever 29 February falls inside the gap. That is why August 21 works its way around the week rather than repeating on a tidy schedule.
