Long weekends 2027

3 times a public holiday lies close to a weekend – with a little leave it becomes a long weekend:

Take leave	Off	Days of leave	Days off	Ratio	Occasion
Tue 22 Jun, Wed 23 Jun, Thu 24 Jun, Fri 25 Jun	19 Jun – 27 Jun 2027	4	9	2.3	Midwinter Day
Mon 29 Nov, Tue 30 Nov	27 Nov – 1 Dec 2027	2	5	2.5	Antarctica Day
Thu 2 Dec, Fri 3 Dec	1 Dec – 5 Dec 2027	2	5	2.5	Antarctica Day

Counted are gaps of up to four working days between a public holiday and the weekend or another public holiday. "Ratio" = days off per day of leave. Weekends follow the local working week.

Dates are generated from the open-source library python-holidays and automatically cross-checked against Nager.Date and the public Google Calendar holiday calendars; every holiday on a working day must be confirmed by a second source. Official announcements take precedence, especially for holidays that depend on the moon or are declared at short notice.
