August 2027 has 31 days, running Sunday, August 1 through Tuesday, August 31. It contains no federal holiday, so all 22 of its weekdays are working days.
August is one of only two months in 2027 with no entry in the federal holiday schedule; March is the other.
It compensates astronomically: the month holds five primary moon phases rather than four, opening with a new moon on August 2 and closing with a second on August 31.
That second new moon is a black moon, the only one of 2027.

Why August has no federal holiday
The eleven statutory holidays in 5 U.S.C. 6103 cluster around historical anniversaries, seasonal markers and labour observances, none of which fall in August.
The gap runs 63 days in 2027, from Independence Day observed on Monday, July 5 to Labor Day on Monday, September 6 — the longest stretch of the year without a federal closure.
August 2027 calendar closures by institution
| Institution | Any date in August 2027 |
|---|---|
| Federal offices | Open every weekday |
| Banks and Federal Reserve | Open every weekday |
| U.S. Postal Service | Open every weekday |
| NYSE and Nasdaq | Open every weekday |
| State offices | Open, with limited local exceptions |

The only significant variation is school start dates. Districts in the South and Southwest commonly begin in the first two weeks of August, while much of the Northeast and Midwest waits until after Labor Day.
Events in August 2027
Month-long observances running through all of August 2027:
- National Immunization Awareness Month
- National Breastfeeding Month
- Children’s Eye Health and Safety Month
- National Wellness Month
Women’s Equality Day on Thursday, August 26 commemorates the certification of the Nineteenth Amendment in 1920.
It has been marked by presidential proclamation since 1973 and is not a federal holiday.
August is the transition month for the American academic year. Most southern districts and many universities begin classes before Labor Day; the rest begin after.
There is no national pattern and the split does not follow state lines cleanly.
August 2027 brings peak late-summer astronomical events, significant Hindu festivals honoring sibling bonds and divine births, and the shift from Leo’s solar fire to Virgo’s grounded precision.

How many days, weeks and working days in August 2027
August 2027 has 31 days, 4 full weeks plus 3 days, 22 weekdays, and 22 working days, because no federal holiday falls in the month.
The calculation:
- August always has 31 days.
- 31 ÷ 7 gives 4 complete weeks with 3 days remaining.
- Nine of the 31 days fall on a Saturday or Sunday, leaving 22 Monday-to-Friday weekdays.
- No federal holiday falls in August, so the weekday count and the working-day count are identical: 22.
August 2027 shares the highest working-day count of the year with March, which also has no federal holiday but carries 23 weekdays.
August 2027 calendar weekday counts

| Monday | 5 |

Five Mondays with no federal holiday among them. Any recurring Monday commitment occurs five times in August 2027 without exception, which is unusual — most months with five Mondays lose one to a holiday.
August 2027 calendar week numbers and day-of-year positions

| New Moon | Monday, August 2 | 6:05 a.m. EDT |
| First Quarter | Monday, August 9 | 12:54 a.m. EDT |

The August 2027 black moon
A black moon is a second new moon within a single calendar month — the direct counterpart to a blue moon, which is a second full moon. August 31, 2027 is the only one in 2027.
It happens because the synodic month runs about 29 days 12 hours 44 minutes against a 31-day calendar month.
Whenever the first new moon falls in the opening two days of a long month, a second one fits before the month ends. August 2027 qualifies with a new moon on the 2nd.
There is nothing to see. A new moon is not visible from Earth, so the only observable effect is an unusually dark sky at the end of the month — good conditions for deep-sky observation and for the Perseid meteor shower’s late stragglers.
