5 things worth knowing about state calendars holidays

What to take away

A state holiday is created by that state's own statute or proclamation, and binds only what the text names: offices, courts, schools, or rarely every employer.
For a count, the governing set is the union of the federal list and each applicable state list, not the state list alone.
Texas closes on Tuesday, March 2, 2027, and Nevada on Friday, October 29, 2027, with no federal holiday either day.
Court and IRS rules can extend a deadline past a day your calendar marks as open, so the rule outranks the spreadsheet.

A 2027 state list is built by reading each state's statute or published schedule, recording who it closes, and adding those days to the federal layer before any count.

Five things a 2027 state list has to get right

The enacting instrument, and the reach written into it.
The state, territory or district it covers, and the year it applies to.
The days it adds to the federal list, named and dated.
The rule that extends a period ending on a closed day.
The version and retrieval date, so a stale answer shows up as stale.

Most states fix their paid holidays in statute and let the governor add days by proclamation. The working list arrives in a state human-resources or administrative-services schedule for the coming year.

OPM's federal holiday list covers the national layer and says nothing about a Texas office in March. That base layer is set out in country calendars, minus the hype in 2027, which is the right starting point before states add days.

Named 2027 state holidays and the reach each one states

State or district	Holiday	2027 date	Who the instrument closes
Texas	Texas Independence Day	Tuesday, March 2	State offices; private employers may choose
California	Cesar Chavez Day	Wednesday, March 31	State offices and agencies
Massachusetts, Maine	Patriots' Day	Monday, April 19	State offices; some public schools
District of Columbia	Emancipation Day	Friday, April 16	District government; a legal holiday for federal tax deadlines
Utah	Pioneer Day	Saturday, July 24	State offices
Hawaii	Statehood Day	Friday, August 20	State offices and public schools
Alaska	Alaska Day	Monday, October 18	State offices
Nevada	Nevada Day	Friday, October 29	State offices

Check the last column first. A list of dates with no reach field cannot tell you whether a payment, a filing or a shipment is affected, and that gap is what moves deadlines without notice. The union arithmetic joining these rows to the federal layer sits in state calendars formula beyond the obvious.

Reach decides how much a date matters

Reach in the instrument	Typical effect
State offices	Permits and filings pause; private business continues
State courts	Filing deadlines move; commercial deadlines usually do not
Public schools	No effect on a statutory deadline
Every employer in the state	Rare, and stated explicitly where it exists

The same date carries four meanings across those rows. A calendar that drops the reach column invites the widest reading, which is how a deadline shifts quietly. Court layers are strictest, because the court's rule can add days the office schedule never mentions.

Reach of a Regional Closure

Reach

Public offices: Filings and permits pause
Courts: Filing deadlines move
Schools: No effect on any deadline
All employers: Rare

Typical effect

Public offices: Private business does not
Courts: Commercial deadlines usually do not
Schools: Frequently confused with others
All employers: Always stated explicitly

Example: a Texas filing a federal calendar calls open

A state agency filing in Austin is due Tuesday, March 2, 2027.

The federal calendar shows nothing that week, so a federal-only count treats March 2 as open.
Texas state offices are closed for Texas Independence Day, so the office cannot accept the filing.
The period runs to Wednesday, March 3, the next day that is neither a weekend nor a holiday.

A state holiday rarely adds a day to a period. It moves the last open day forward, and only for obligations the instrument reaches.

A federal-only count reports that deadline one day early. The same slip appears whenever a state date lands inside a short period, which is why the habits in state calendar mistakes that quietly move a real deadline without notice are worth building early.

Court rules and tax rules that extend a count

Federal civil deadlines follow Rule 6 of the Federal Rules of Civil Procedure, which continues a period to the next day that is not a Saturday, Sunday or legal holiday. State and local rules often name their own holidays on top.

Tax deadlines use a different list. IRS Publication 509 prints the federal tax calendar and defines which days count as legal holidays for due dates, including District of Columbia Emancipation Day. Where a rule like either of those governs, the calendar must be built to match it.

Six fields to record for every row

Enacting bodythe statute, order or schedule behind the day.
Reachwhom the instrument closes.
Regionstate, territory or district.
Effective periodthe year or range covered.
Retrieved onthe date you pulled the list.
Versionthe revision you are quoting.

Fields for a Sub-National List

Enacting body prevents summary as source
Reach prevents courts list on payment
Region prevents neighboring list by accident
Effective period prevents reusing last year
Retrieved on prevents stale answer as broken formula
Version prevents two people meaning different things

Keep the state layer separate from the federal one at rest, because a merged list cannot say which layer closed a day. State lists also change later than federal ones, so recompute rather than carry January's answer into October.

The base count underneath is explained in which leftover-day rule decides a year's exact working-day total.
