Federal holidays this week

None of the US federal observed holidays fall in this ISO week.

All 2016 holidays

ISO week 4 of 2016 (2016-W04) runs Monday, January 25, 2016 through Sunday, January 31, 2016. The full range is Jan 25 – Jan 31, 2016. Days follow the ISO Monday–Sunday convention. The US week label for dates in this window is 5–6. This spoke is the seven-day operations page for one week—not the 2016 matrix of all weeks, and not the hub that shows “today’s” US and ISO numbers side by side.

Federal holidays in this window: No federal holidays. This week stays within a single calendar year. When a holiday shifts observance to a nearby weekday, the table shows the date offices actually close rather than the statutory calendar date alone. The week number 4 does not increment or skip because a Monday is dark; only the working-day count inside Jan 25 – Jan 31, 2016 changes.

ISO versus US labels for this window

ISO weeks always start on Monday and end on Sunday. US week numbers on this site often follow a Sunday-start convention used in retail and broadcast schedules. Both labels appear here so a report that says 2016-W04 can be matched to a partner file that says US week 5–6. They can disagree, especially when Monday, January 25, 2016 or Sunday, January 31, 2016 sits in late December or early January.

If two teams merge timesheets this week, write both labels in the shared note for Jan 25 – Jan 31, 2016. Do not assume “week 4” is unambiguous. The ISO year inside 2016-W04 is the durable key; the civil year printed on a paycheck can differ on cross-year days. This week stays within a single calendar year.

Day-by-day breakdown

The grid lists all seven days with weekday names, calendar dates, and day-of-year numbers. That layout is for comparing ISO bounds against month-end billing cycles, school weeks that start on Sunday, or a pay period that ends on Thursday. Each row still belongs to 2016-W04 even if the month name changes mid-week. Payroll teams often map ISO weeks to pay periods even when checks are issued on a different weekday.

Download an ICS calendar file for this week to import the range into Outlook, Google Calendar, or Apple Calendar. The file contains one all-day event spanning Monday, January 25, 2016 through Sunday, January 31, 2016. It is a planning block, not a meeting invite: no clock times, no time zone conversion. After import, overlay actual meetings as separate timed events.

Holidays, capacity, and this week’s work

No federal holidays If the list is empty, treat Jan 25 – Jan 31, 2016 as a standard seven-day civil span and apply company holidays separately. If a federal observed day sits on Monday, shipping cutoffs that assume five full warehouse days will miss. Capacity planners should count the remaining weekdays after holidays, not divide the week’s volume by five by habit.

Confirm closures against 2016 US holidays when a customer SLA cites “next business day” inside this week. The spoke lists federal observed dates that fall in Jan 25 – Jan 31, 2016; it does not interpret a private employer’s floating holiday policy.

Stepping to adjacent weeks

Use previous week and next week to walk 2016 one ISO week at a time. Sprint reviews, incident windows, and production batches that are already numbered as consecutive weeks should move with those links rather than re-typing dates. Open the full 2016 week table when the next need is a jump to an arbitrary week number instead of a neighbor.

At year edges, previous or next may land in an adjacent ISO year. That is expected. 2016-W04 is still the title of this page; the neighbor page will carry its own label. Do not copy Monday, January 25, 2016 from this page onto a neighbor’s ticket.

Printable month context

When this week straddles two month names, a single ISO row is a poor poster. Download the 2016 yearly calendar for a sheet with all twelve months and week columns, or open a monthly calendar with larger day cells and highlight Monday, January 25, 2016 through Sunday, January 31, 2016 by hand. The spoke remains the source of the ISO bounds; the month sheet is the visual overlay.

Teachers and coaches who publish “week of” handouts should paste Jan 25 – Jan 31, 2016 in the header and keep weekday names in the body. Parents who think in Sunday-start weeks can read the US label 5–6 without converting the ISO title. Putting both on the handout prevents the Sunday-night email that asks whether Monday is in “this week.”

Tickets, cartons, and incident windows

A warehouse stamp that reads 2016-W04 is a claim about Jan 25 – Jan 31, 2016. Receiving should reject a pallet only after confirming both the ISO year inside the label and the Monday date Monday, January 25, 2016. A Jira fix version named “W4” should paste Jan 25 – Jan 31, 2016 in the description so support knows the deploy window. An incident postmortem that cites “week 4” should link this spoke so readers see the seven civil days, not a floating number.

If this week straddles a month-end close, finance still books by civil date; the ISO label is only the grouping key. Write 2016-W04 on the close checklist and keep invoice dates on the day rows. Mixing those two clocks is how a Thursday invoice lands in the wrong weekly dashboard.

What this week page is not

It is not a converter that turns an arbitrary week number into dates from a blank form—that is the week-dates tool. It is not a definition essay about why ISO exists; the hub covers the two standards in the large. It is the concrete span Jan 25 – Jan 31, 2016 for 2016-W04, with holidays, ICS, and neighbor links. Use it when a ticket, carton, or sprint already says week 4 and someone needs the seven civil days behind that stamp.

Frequently asked questions

What dates are in ISO week 4 of 2016?

ISO week 4 (2016-W04) runs Monday, January 25, 2016 through Sunday, January 31, 2016, Monday through Sunday. The full range is Jan 25 – Jan 31, 2016. The US week label for dates in this window is 5–6. This spoke is the seven-day operations page for one week, not the full-year matrix and not the hub that shows today’s two standards.

When does this ISO week disagree with the US week label?

ISO weeks start Monday; many US labels start Sunday. They can disagree, especially when Monday, January 25, 2016 or Sunday, January 31, 2016 sits in late December or early January. Write both 2016-W04 and US week 5–6 in a shared note for Jan 25 – Jan 31, 2016. The ISO year inside the label is the durable key when a paycheck year differs.

How do I add this week to a calendar app?

Download the ICS file from this page. It creates one all-day event spanning Monday, January 25, 2016 through Sunday, January 31, 2016 for 2016-W04. Import it into Outlook, Google Calendar, or Apple Calendar as a planning block, then overlay timed meetings separately. The file has no clock times and does not convert time zones.

Is a federal holiday inside this week a reason to renumber it?

No. Federal holidays in this window: No federal holidays. Observed dates may close offices, but week 4 does not skip or increment. Only the working-day count inside Jan 25 – Jan 31, 2016 shrinks. Confirm closures against the year’s US holiday list when a customer SLA cites the next business day inside this week.

Why does a cross-year note appear on some week pages?

ISO weeks can begin in the previous December or end in the next January. Note for this week: This week stays within a single calendar year. The day table shows each civil date. A timesheet dated 31 December may belong to week 1 of the next ISO year. Copy 2016-W04, not only the civil year printed on a check.

What should a handout print besides week 4?

Paste Jan 25 – Jan 31, 2016 in the header and keep weekday names in the body. Parents who think in Sunday-start weeks can also read US week 5–6. Putting both labels on a “week of” sheet prevents the Sunday-night email that asks whether Monday is in this week. Neighbor links step one ISO week at a time.
