December 2027 at a Glance
December runs on two calendars at once: a compressed working month with year-end deadlines, and a social month full of gatherings, school performances and travel. Printing December early is the single most useful planning habit of the year, because the free days disappear faster than expected.

Holidays and Observances in December 2027
December 2027 contains 1 federal holiday: Christmas Day on Saturday, December 25.
The rest of December fills quickly: Christmas Eve on the 24th, Hanukkah on dates set by the Hebrew calendar, Kwanzaa beginning on the 26th, the winter solstice around the 21st and New Year's Eve on the 31st. The final two weeks run at reduced staffing across most industries.

Planning Tips for December 2027
Count your real working days
Between holidays, closures and reduced staffing, December typically offers far fewer usable working days than its 31-day length suggests. Counting them on the grid changes what you commit to.
Fix the gathering dates first
School concerts, office parties and family meals compete for the same three weekends. Locking the fixed ones in before the month begins is what prevents the mid-December double-booking.
Set up January before the year ends
The last week of December is quiet enough to prepare the year ahead — print January, mark the known dates, and start the new year with a calendar that is already working.
How Many Working Days Are in December 2027?
December 2027 contains 23 working days once weekends and federal holidays are
removed from its 31 calendar days. These figures assume a standard Monday-to-Friday schedule;
shift and weekend workers will count differently.

Payroll periods, project estimates and billable-hour targets all depend on this number, and it varies by
several days from month to month — which is why estimating "about 22 days" every month quietly
distorts a quarter's planning.
Week Numbers in December 2027
December 2027 spans ISO week 48 through week 52. Under the ISO 8601 standard used across Europe and by
most project-management and payroll software, weeks run Monday to Sunday and week 1 is the week containing the
first Thursday of the year.
| Week number | Starts (Monday) | Ends (Sunday) |
|---|
| Week 48 | November 29 | December 5 |
| Week 49 | December 6 | December 12 |
| Week 50 | December 13 | December 19 |
| Week 51 | December 20 | December 26 |
| Week 52 | December 27 | January 2 |
If your workplace refers to "week 48" or "W52", these are the dates it means.
Our guide to how many weeks are in a year explains why some years
carry 53 numbered weeks and how the ISO rule decides where week 1 begins.
Note that American calendars usually start the week on Sunday, so a US week-of-the-year count can differ by one
from the ISO numbering above — you can switch the grid between Sunday and Monday starts using the
Week starts menu above.
