When is Summer Solstice 2027?
Summer Solstice 2027 is on Monday, 21 June 2027 — Monday. That is 222 days from today (11 November 2026) — 31 weeks and 5 days, or about 7.3 months. It is a Seasonal observance.
How the countdown is worked out
The countdown is the number of days from today to the holiday's date: Monday, 21 June 2027 minus 11 November 2026 is 222 days. The count is in calendar days — it counts the days you have to wait, not the number of midnights, and it does not count today. The countdown timer recomputes the number live, second by second, and the days until calculator does the same calculation for any date you choose. If the holiday is in a different time zone from you, the day starts at a different moment — but the date is the date, and the countdown is in days, so the time zone does not change the number.
What is Summer Solstice?
The summer solstice is the longest day of the year in the Northern Hemisphere (around 21 June) — and the shortest in the Southern Hemisphere. It marks the start of astronomical summer in the north.
How Summer Solstice is observed
People gather at Stonehenge in England, celebrate Midsummer in Scandinavia with maypoles and bonfires, and hold solstice festivals around the world.
How the date is worked out
Summer Solstice is a moveable observance: its date changes from year to year. The table below gives the dates for 2026, 2027 and 2028, so you can see the pattern — and for planning more than a year ahead, use the days until calculator with the date for the year you need.

Summer Solstice 2027 in the calendar
Summer Solstice 2027 is the 172nd day of 2027 — a year of 365 days — and it falls in ISO week 25 of the year. There are 193 days left in the year after it, and 30 days in June 2027. In the Northern Hemisphere it is summer; in the Southern Hemisphere the seasons are reversed.
The week number matters more than people think: in business and government across Europe, dates are often given as week numbers, and the week number finder gives the ISO week for any date. The day-of-year number is used in astronomy, in logistics and in some payroll systems. And the days-left figure is the useful one for planning the rest of the year: after Summer Solstice 2027 there are 193 days — 27 weeks — left in 2027.
Planning for Summer Solstice 2027
222 days is 7 months — plenty of time to plan. If Summer Solstice means travel, book it now: fares and hotels are usually cheapest months in advance, and the popular dates sell out. If it means time off work, put the request in early, especially if the holiday falls on a weekday — Monday is a working day for most people, so the day off needs to be booked. And if it means gifts or preparations, the countdown is long enough that a little planning each week is worth more than a rush in the last few days.
Summer Solstice 2027 falls on a Monday — a weekday — so most people need to take the day off to mark it properly. Book the time off early, especially if the holiday is one people travel for: the days around a weekday holiday are among the busiest travel days of the year, and the fares rise as the date approaches.
The countdown in other units
The countdown to Summer Solstice 2027 is 222 days — which is 31 weeks and 5 days, 5328 hours, 319,680 minutes, or about 7.3 months. Of those 222 days, 158 are weekdays and 64 are weekend days — so if you are counting working days, there are 158 of them left before the holiday. The days between dates calculator works out the same numbers for any two dates, and the business days calculator counts the working days excluding public holidays.
Summer Solstice around the world
As a seasonal marker, this day is fixed by astronomy, not by any calendar or government: it is the equinox or the solstice, the day the Earth's tilt puts the Sun in a particular place. The date moves by a day from year to year (around 20–22 March, June, September and December), and it is marked by festivals and traditions around the world rather than by a public holiday.
