Printable Blank September 2027 Calendar
Sometimes only the dates are needed. A blank sheet keeps the September 2027 grid, Wednesday the 1st to Thursday the 30th, and leaves every box free for your own notes.
🗒️ Making a blank September sheet
- Go up to the builder and switch on Blank Calendar, just beneath the title box.
- Holidays, holiday names, moon icons, week numbers, weekend shading and notes lines all switch off together.
- Set the paper size, orientation, week start and colour you want.
- Save as PDF, PNG or JPG, or print directly.
- Need one extra, say weekend shading? Turn on only that option and the others stay off.
✏️ Where a blank September page helps
- Back-to-school planning: jot timetables, pick-up rotas and homework deadlines by hand.
- Sports and club fixtures: add autumn league dates that no holiday list would include.
- Local closures: mark state, county or workplace days off the built-in lists skip.
- Light on ink: a plain grid prints quickly and cheaply.

Why September Has the Name It Does
A month called “seven” that sits in ninth place has a story behind it. Here are the steps that shaped the month.
September was the seventh month
Rome's early calendar began in March and ran ten months. September took its name from septem, Latin for seven, because it was the seventh in that sequence.
The year begins in January
Once the Roman year opened in January, September slid to ninth place. Its name, like October, November and December, kept counting from the old March start.
The Julian reform sets 30 days
Julius Caesar's calendar gave September 30 days, the length it has held ever since, and later reforms never altered it.
An emperor tries a new name
Domitian reportedly renamed September “Germanicus” to honour a military title. The change did not outlive him and the old name returned.
Britain skips eleven days
When Britain and its colonies adopted the Gregorian calendar, Wednesday, September 2 was followed by Thursday, September 14.
Other Calendars in Play This September
This page follows the Gregorian calendar, but several other systems shape festivals and new years around the same weeks.
Gregorian Calendar
Solar · 365/366 days
The system behind this page. September has 30 days and, in 2027, opens on a Wednesday. It is the civil calendar for most governments and schools.
Hebrew Calendar
Lunisolar · 353–385 days
September 2027 falls mostly in Elul, the month of preparation. Rosh Hashanah, the Hebrew new year, begins at sundown on Friday, October 1.
Chinese Calendar
Lunisolar · 353–385 days
Each month starts on a new moon, so the 15th lands on a full moon. That is why the Mid-Autumn Festival falls on September 15 in 2027.
Hindu Calendar
Lunisolar · varies by system
September 2027 covers part of Bhadrapada. Ganesh Chaturthi (September 4) follows the lunar tithi, while Kerala's Onam (September 12) is reckoned by the solar month of Chingam.
Ethiopian Calendar
Solar · 365/366 days
Twelve 30-day months plus a short thirteenth. The new year, Enkutatash, usually starts on September 11 and moves to September 12 in the year before a Gregorian leap year, as in 2027.
Islamic (Hijri) Calendar
Lunar · 354/355 days
Twelve lunar months with no solar correction, so the calendar shifts roughly eleven days earlier against the Gregorian year each time and September dates never line up with the same Hijri month twice in a row.
Does September Ever Change Length?
Never. September is one of four months with 30 days (April, June, September and November), and leap years only touch February.
📅 Common Year (2027)
February has 28 days and September its usual 30. September 1, 2027 is a Wednesday; a year later, in leap year 2028, it moves ahead two weekdays to a Friday.
🐸 Leap Year
February gains a 29th day to keep pace with the roughly 365.2422-day orbit. September stays at 30 days but starts one weekday later than it otherwise would.
The three-step leap year test
Together the steps average 365.2425 days per year, close enough to the real orbit that the seasons stay in place for thousands of years.
Getting a Sharp September Printout
A few settings decide whether the page prints crisp and complete or cropped and soft.

Students & Teachers
Map out the first weeks of term, assessment dates and September project deadlines.
Families
Track school runs, club sign-ups, harvest-season outings and birthdays on the fridge.
Finance & Ops Teams
September 30 closes the third quarter, so a printed month keeps invoicing and reporting cut-offs in view.
Event Planners
Line up autumn fairs, Oktoberfest travel or Ryder Cup viewing against holiday dates.
September Trivia Worth Knowing
Nine quick facts about the month, checked against the calendar.
The name comes from septem, Latin for seven, yet September is the ninth month. It is a leftover from the March-start Roman year.
September 2027 begins on a Wednesday and ends on a Thursday, which gives it five Wednesdays and five Thursdays and four of every other weekday.
September is one of four 30-day months, alongside April, June and November, and its length never changes in leap years.
The traditional birthstone is sapphire, and the birth flowers are the aster and the morning glory.
In September 1752 Britain and its colonies went from Wednesday the 2nd straight to Thursday the 14th, dropping eleven days to adopt the Gregorian calendar.
The equinox at about 06:01 UTC on September 23, 2027 brings near-equal day and night and swaps the seasons between the hemispheres.
The Harvest Moon is the full moon closest to the September equinox. In 2027 that is the September 15 full moon, eight days ahead of the equinox.
Astrologers place Virgo through roughly September 22 and Libra from about September 23, so the sign changes around the equinox.
September 27 to October 3 forms ISO week 39, so that week straddles two months and would split across two pages in a weekly layout.
September and Calendar Myths, Checked
Some popular claims about the month do not hold up.
Labor Day on the first Monday of September is celebrated worldwide.
Only the US and Canada hold it then. Much of the world marks workers on May 1, and Australian states pick their own dates.
On the equinox, day and night are exactly 12 hours each.
Close, but not exact. Atmospheric refraction and the way sunrise is defined make the day slightly longer, and the truly equal day falls a few days later, depending on latitude.
The Harvest Moon is bigger and always orange.
It is the same size as any full moon. Its trademark is rising soon after sunset on several nights in a row, and it looks orange only when low in a hazy sky.
Autumn starts on September 1 everywhere.
That is only the meteorological convention for the north. Astronomical autumn begins at the equinox, and south of the equator September marks the start of spring.
September is called that because it is the seventh month.
It was the seventh month in the March-start calendar, but has been the ninth since the year began in January.
Riots broke out over Britain's 'stolen' eleven days in 1752.
Historians find little evidence of it. The story leans on a slogan in a Hogarth painting rather than on records of unrest.
One Month, Four Different Moods
September flips the seasons between hemispheres and marks turning points in the tropics too.
Autumn
Northern HemisphereFrom September 1 meteorologists count autumn across North America, Europe and northern Asia, with cooling nights, changing leaves and shorter days once the equinox passes.
Spring
Southern HemisphereIn Australia, New Zealand, southern Africa and southern South America, September brings spring: longer days, blossom and warming weather.
Monsoon Retreat
South AsiaThe southwest monsoon usually starts withdrawing from north-west India in the second half of September, though heavy rain often continues in other regions.
Storm Season Peak
Atlantic & tropicsThe Atlantic hurricane season reaches its statistical peak around September 10, so travel and outdoor plans in the region deserve a weather check.
September 2027 Festivals and Events
Six September happenings worth pencilling in, with their 2027 dates.
Labor Day (Sep 6)
The first Monday of September closes the traditional summer season, with parades, barbecues and end-of-summer sales, and in many places it marks the real start of the school year.
Ganesh Chaturthi (Sep 4)
Homes and neighbourhood pandals install clay Ganesha idols in a festival that runs several days in many cities, including Hyderabad, Mumbai and Pune, ending with processions and immersion.
Onam (Sep 12)
Thiruvonam day is the high point of Kerala's harvest festival, celebrated with floral carpets called pookalam and a multi-course vegetarian feast on banana leaves.
Mid-Autumn Festival (Sep 15)
Families gather to share mooncakes and admire the full moon, and the same night carries the Harvest Moon in 2027. Vietnam, Japan and Korea keep related traditions.
Ryder Cup (Sep 17–19)
The 46th Ryder Cup, marking the event's 100th anniversary, pits Europe against the United States, with practice days from September 13.
