Holiday collections are optional. You can use a blank calendar, add your own events or include the reviewed U.S. federal collection. A collection’s source, date roles and coverage range are part of the information you need to read it correctly.
Choose a collection or leave holidays off
Open the calendar settings and review the holiday collection choice. None keeps the calendar free of collection entries. Selecting the U.S. federal collection adds its verified dates within the selected calendar range. Your own events remain separate from those source entries.
The collection covers U.S. federal statutory holidays and standard Monday-through-Friday observance. It does not claim to include every U.S. holiday, state or local date, religious observance, school closure or business schedule. Use the relevant organization’s own information when you need to know whether it will be open.
Read actual and observed dates separately
An actual date identifies the holiday. An observed date can differ when the official schedule applies a weekend observance rule. For example, Independence Day 2027 is July 4, while the standard observed date is July 5. Keep the observed label visible if you display that date.
Review the date-role setting before printing or exporting. When actual and observed dates coincide, the calendar should not present them as two unrelated holidays. When they differ, check which one you want to emphasize without changing the underlying official record.
Check the reviewed coverage
The current reviewed collection covers holiday years 2026, 2027 and 2028. Its source is the U.S. Office of Personnel Management, with the review recorded on the Data sources page. This review range is independent of the editor’s wider 1900–2100 date support.
A calendar can have valid dates outside the holiday collection. In a 2028–2029 academic calendar, the 2029 portion therefore needs a visible coverage note until those holiday records have been reviewed separately. The absence of entries in that portion must not be interpreted as a complete holiday list for 2029.
Check dates near a year boundary
New Year’s Day 2028 has an actual date of January 1, 2028 and a standard observed date of December 31, 2027. A December 2027 calendar needs to consider that observed date even though the associated holiday year is 2028.
Read the full displayed date when reviewing the end of a year. A source record’s named holiday year and the date visible in the grid can differ. Do not move the observance to December 2028 or rename January 1 merely to keep the two entries inside the same calendar-year label.
Keep source context with the output
Review the holiday legend and coverage note in the print or download preview. The person reading a PDF may not have seen the collection settings in the editor. Preserve the distinction between your own events and the optional official collection.
If a month has no entries from the selected collection, you can still add your own relevant dates. March 2027 has no dates in the reviewed U.S. federal list. That fact does not rule out personal events, local observances or dates supplied by your school or workplace.
