Ten Straight Days off

Ten Straight Days off

Japan has consecutive holidays called "Golden Week," and its period is ten days in 2019.

The details are shown as follows:

April 27 (Sat) ... Saturday
April 28 (Sun) ... Sunday
April 29 (Mon) ... Shōwa Day
April 30 (Tue) ... National Holiday
May 1 (Wed) ... Enthronement of the Crown Prince
May 2 (Thu) ... National Holiday
May 3 (Fri) ... Constitution Day
May 4 (Sat) ... Greenery Day
May 5 (Sun) ... Children's Day
May 6 (Mon) ... Substitute Holiday

Since the Crown Prince was enthroned on May 1, this day became a national holiday only in 2019.

In addition, a weekday between national holidays also becomes a national holiday according to Japanese law, so both April 30 and May 2 became holidays.

Furthermore, when a national holiday coincides with Sunday, next Monday becomes a substitute holiday, so May 6 became a holiday.

Due to the overlapping of several factors, it has become such a long holiday.

10連休

日本にはゴールデンウィークと呼ばれる連休があり、2019年は10連休となりました。

その内訳は下記のとおりです。

4月27日（土）・・・休日
4月28日（日）・・・休日
4月29日（月）・・・昭和の日
4月30日（火）・・・国民の休日
5月1日（水）・・・皇太子殿下即位・改元
5月2日（木）・・・国民の休日
5月3日（金）・・・憲法記念日
5月4日（土）・・・みどりの日
5月5日（日）・・・こどもの日
5月6日（月）・・・振替休日

5月1日に皇太子殿下が即位されたため、2019年に限りこの日が祝日となりました。

そして日本では祝日に挟まれた平日は「国民の休日」となるため、4月30日と5月2日が休みとなります。

さらに、祝日と日曜日などが重なった場合は、休日が減らないよう次の平日を「振替休日」とする制度があるため、5月6日も休みとなります。

幾つかの要素が重なり合って、このような長い連休になったというわけです。

• Japan has consecutive holidays called "Golden Week," and its period is ten days in 2019.
• Japan has several consecutive holidays called "Golden Week," and its period is ten days long in 2019.

  The word "long" is not strictly needed here, but does help it flow a bit better.

• Since the Crown Prince was enthroned on May 1, this day became a national holiday only in 2019.
• Since the Crown Prince was enthroned on May 1, this day is a national holiday only in 2019.ORSince the Crown Prince was enthroned on May 1, this day became national holiday starting in 2019.

  "Became" is not wrong here, but could be a bit vague. If this is a holiday in 2019 and no other year, I would use "is a". If this is a holiday in 2019 and will continue to be a holiday in 2020 and onward, I would use "starting in".

• Japan has consecutive holidays called "Golden Week," and its period is ten days in 2019.
