Since January 1, 1873, Japan has used the Gregorian calendar, with local names for the months and mostly fixed holidays. Before 1873, a lunisolar calendar was in use, which was adapted from the Chinese calendar. Japanese eras are still in use.
Since the adoption of the Gregorian calendar, three different systems for counting years have or had been used in Japan:
- The Western Anno Domini (Common Era) (西暦, seireki) designation
- The Japanese era name (年号, nengō) based on the reign of the current emperor, the year 2007 being Heisei 19
- The imperial year (皇紀, kōki) based on the mythical founding of Japan by Emperor Jimmu in 660 BC.
The modern Japanese names for the months literally translate to "first month", "second month", and so on. The corresponding number is combined with the suffix -gatsu (month):
- January - 一月 (ichigatsu)
- February - 二月 (nigatsu)
- March - 三月 (sangatsu)
- April - 四月 (shigatsu)
- May - 五月 (gogatsu)
- June - 六月 (rokugatsu)
- July - 七月 (shichigatsu)
- August - 八月 (hachigatsu)
- September - 九月 (kugatsu)
- October - 十月 (jūgatsu)
- November - 十一月 (jūichigatsu)
- December - 十二月 (jūnigatsu)
In addition, every month has a traditional name, still used by some in fields such as poetry; of the twelve, shiwasu is still widely used today. The opening paragraph of a letter or the greeting in a speech might borrow one of these names to convey a sense of the season. Some, such as yayoi and satsuki, do double duty as given names (for women). These month names also appear from time to time on jidaigeki, contemporary television shows and movies set in the Edo period or earlier.
The name of month: (pronunciation, literal meaning)
- January - 睦月 (mutsuki, affection month)
- February - 如月 or 衣更着 (kisaragi or kinusaragi, changing clothes)
- March - 弥生 (yayoi, new life; the beginning of spring)
- April - 卯月 (uzuki, u-no-hana month; the u-no-hana is a flower, genus Deutzia)
- May - 皐月 or 早月 or 五月(satsuki, fast month)
- June - 水無月 (minatsuki or minazuki, month without water — the na is actually a possessive particle and the 無 character is ateji)
- July - 文月 (fumizuki, book month)
- August - 葉月 (hazuki, leaf month)
- September - 長月 (nagatsuki, long month)
- October - 神無月 (kaminazuki or kannazuki, month without gods), 神有月 or 神在月 (kamiarizuki, month with gods – used only in Izumo province, where all the gods are believed to gather in October for an annual meeting at the Izumo Shrine).
- November - 霜月 (shimotsuki, frost month)
- December - 師走 (shiwasu, priests run; it is named so because priests are busy making end of the year prayers and blessings.)
Subdivisions of the monthEdit
Japan uses a seven-day week, aligned with the Western calendar. The seven day week, with names for the days corresponding directly to those used in Europe, was brought to Japan around 800 AD. The system was used for astrological purposes and little else until 1876, shortly after Japan officially adopted the Western calendar. Fukuzawa Yukichi was a key figure in the decision to adopt this system as the source for official names for the days of the week. The names come from the five visible planets, which in turn are named after the five Chinese elements (wood, fire, earth, metal, water), and from the moon and sun (yin and yang).
Japan also divides the month roughly into three 10-day periods. Each is called a jun (旬). The first is jōjun (上旬); the second, chūjun (中旬); the last, gejun (下旬). These are frequently used to indicate approximate times, for example, "the temperatures are typical of the jōjun of April"; "a vote on a bill is expected during the gejun of this month."
Days of the monthEdit
Each day of the month has a semi-systematic but irregularly formed name:
|1||一日||tsuitachi (sometimes ichijitsu)||17||十七日||jūnananichi|
|4||四日||yokka||20||二十日||hatsuka (sometimes nijūnichi)|
Tsuitachi is a worn-down form of tsukitachi, which means the first of the month. In the traditional calendar, the thirtieth was the last day of the month, and its traditional name, 晦日 misoka, survives (although sanjūnichi is far more common, and is the usual term). The last day of the year is 大晦日 ōmisoka (the big thirtieth day), and that term is still in use.
National holidays Edit
Notes: Single days between two national holidays are taken as a bank holiday. This applies to May 4, which is a holiday each year. When a national holiday falls on a Sunday the next day that is not a holiday (usually a Monday) is taken as a holiday.

- 2009 - September 22 may become sandwiched between two holidays, which would make this day a national holiday.
Seasonal days Edit
Some days have special names to mark the change in seasons. The 24 Sekki (二十四節気 Nijūshi sekki) are days that divide a year in the Lunisolar calendar into twenty four equal sections. Zassetsu (雑節) is a collective term for the seasonal days other than the 24 Sekki. 72 Kō (七十二候 Shichijūni kō) days are made from dividing the 24 Sekki of a year further by three. Some of these names, such as Shunbun, Risshū and Toji, are still used quite frequently in everyday life in Japan.

- Shanichi (社日) is the Tsuchinoe (戊) day closest to Shunbun (middle of spring) or Shūbun (middle of fall), which can be as much as -5 to +4 days away from Shunbun/Shūbun.
The following are known as the five seasonal festivals (節句 sekku, also 五節句 go sekku). The Sekku were made official holidays during Edo era.
- January 7 (1/7) - 人日 (Jinjitsu), 七草の節句 (Nanakusa no sekku)
- March 3 (3/3) - 上巳 (Jōshi, Jōmi), 桃の節句 (Momo no sekku)
- 雛祭り (Hina matsuri), Girls' Day.
- Tango (端午): May 5 (5/5)

The rokuyō (六曜) are a series of six days that predict whether there will be good or bad fortune during that day. The rokuyō are still commonly found on Japanese calendars and are often used to plan weddings and funerals. The rokuyō are also known as the rokki (六輝). In order, they are:
- 先勝 (senshō) - Good luck before noon, bad luck after noon. Good day for beginnings (in the morning).
- 友引 (tomobiki) - Bad things will happen to your friends. Funerals avoided on this day (tomo = friend, biki = pull, thus a funeral might pull friends toward the deceased).
- 先負 (senbu) - Bad luck before noon, good luck after noon.
- 仏滅 (butsumetsu) - The day Buddha died. Most unlucky day. Weddings best avoided.
- 大安 (taian) - Most lucky day. Good day for weddings.
- 赤口 (shakkō) - The hour of the horse (11 am - 1 pm) is lucky. The rest is bad luck.
The rokuyō days are easily calculated from the Japanese Lunisolar calendar. Lunisolar January 1st is always senshō, with the days following in the order given above until the end of the month. Thus, January 2nd is tomobiki, January 3rd is senbu, and so on. Lunisolar February 1st restarts the sequence at tomobiki. Lunisolar March 1st restarts at senbu, and so on for each month. The last six months repeat the patterns of the first six, so July 1st = senshō and December 1st is shakkō.
The first day of April has broad significance in Japan. It marks the beginning of the government's fiscal year. Many corporations follow suit. In addition, corporations often form or merge on that date. In recent years, municipalities have preferred it for mergers. On this date, many new employees begin their jobs, and it is the start of many real-estate leases. The school year begins on April 1. (For more see also academic term)
