4-4-5 Retail Calendar

A 4-4-5 retail calendar groups each quarter into three periods of four weeks, four weeks, then five weeks. This page builds a planning-grade 4-4-5 year from the Sunday nearest February 1, in the style used in US retail merchandising discussions. It is not a licensed National Retail Federation file, not an official NRF calendar product, and not a substitute for a paid 4-5-4 subscription table.

Where the five-week period sits

In 4-4-5, the long period is the third period of each quarter. Period 1 has four weeks, period 2 has four, period 3 has five. Inventory and sales in that third period cover more days, so raw period totals are not comparable to the four-week periods without restating to average weekly sales. That restatement is why merchandisers care which pattern they chose.

The sibling 4-5-4 calendar puts the five-week period in the middle of each quarter. The 5-4-4 calendar puts it first. Do not paste a 4-4-5 screenshot into a workbook labeled 4-5-4. The Sunday nearest February 1 start can be shared while the week buckets inside the quarter differ.

Sunday nearest February 1

The retail year here begins on the Sunday closest to February 1. That start can fall in late January or early February depending on the civil calendar. Weeks run Sunday–Saturday in this NRF-style convention, which differs from ISO weeks that start on Monday. A “week 1” on this page is not ISO week 1.

Some 53-week retail years appear when the Sunday-start rule plus 52×7 days does not land the next start cleanly. Extra weeks are typically attached to the last period of the year in planning discussions. This generator is planning-grade: confirm any 53-week treatment against the table your finance team actually books.

How to use this 4-4-5 view

Enter a retail year and calculate. Read period start and end dates, week counts of 4, 4, and 5 inside each quarter, and the civil dates those weeks cover. Map promotions to period 3 knowing it contains five Sundays.

Civil month grids remain useful for landlord calendars and federal holidays. Overlay 2026 holidays on civil dates; retail periods do not rename Christmas. A five-week period that contains Christmas still uses the civil holiday date.

Worked examples

A merchant compares last year’s period-3 jewelry sales to this year’s period 3. Because both periods are five weeks under 4-4-5, they compare period totals more fairly than if one year had been 4-5-4 with the long period in the middle. They still divide by five for a weekly run-rate.

A planner building 2026 ads wants the third period of the third quarter (often the late-year five-week bucket in 4-4-5) and needs its Sunday start. They generate the year here rather than counting four-week blocks on a wall calendar and missing the extra week.

Why this is not the fiscal month calendar

Federal fiscal months starting in October are twelve civil-like months, not 4-4-5 weeks. Retail 4-4-5 is a week calendar. Mixing FY labels with period-3 five-week buckets produces audit confusion. Use the fiscal calendar generator when the audience is federal FY; stay here when the audience is retail periods.

ISO week-number calendars also use weeks but start Monday and define week 1 by January 4. NRF-style weeks start Sunday near February. Those systems disagree on week boundaries. Do not import ISO week numbers into a 4-4-5 workbook.

Licensing and accuracy notes

NRF publishes official 4-5-4 calendars for members. This page approximates the common Sunday-nearest-February-1 construction for education and internal drafts. If a vendor contract cites NRF week numbers, buy or license the official table. Do not cite this HTML as an NRF authority.

Leap days fall inside whichever retail week contains February 29. The extra civil day does not add a retail week by itself; week count follows the Sunday series. Century leap rules still affect which civil date a given Sunday is.

Reporting pitfalls unique to 4-4-5

Period-over-period charts that ignore the five-week close will overstate the last period of every quarter. Always annotate 4 vs 5. Comp-store weekly averages fix most of that distortion. Board slides should say “4-4-5 period 3 (5 weeks)” in the footnote.

Switching from 4-4-5 to 4-5-4 mid-year restates every quarter’s middle and end. Freeze the pattern in the planning memo before generating 2026 versions of ads and packout calendars.

Sunday circulars in period 3

Because period 3 has five weeks, it contains five Sundays. Circular advertising and Sunday traffic models should budget five inserts, not four. Teams that copy a four-Sunday media plan into period 3 under-buy the last Sunday. Footnote the five-Sunday count on the media calendar for 2026 when that year is generated here.

Inventory snapshots taken on the last Saturday of period 3 cover more days of sell-through than a period-1 snapshot. Comparability requires weekly averaging and matching snapshot timing. Under 4-4-5, end-of-quarter snapshots sit at the end of the long period, unlike 4-5-4 where the long period ended in the middle.

Packout calendars

Vendors who pack to retail periods should label cartons with 4-4-5 and the period number, not merely a civil quarter name, so a 4-5-4 customer does not shelve the shipment in the wrong week bucket. The shared February-adjacent Sunday does not make packout weeks identical across patterns.
