Convert one date or week
The Walmart week converter turns a date into its WM week or a WM week into its Saturday-to-Friday range, and the comp week finder lines this year’s week up against last year’s.
TOOLS · CALENDAR
Walmart supplier weeks run Saturday through Friday, arranged in a 4-5-4 month pattern. Each fiscal year below is the full week-by-week table: the WM week code, both dates, the fiscal month and quarter, and the holidays that fall inside the week.
DIRECT ANSWER
FY2027 runs January 31, 2026 to January 29, 2027, 52 weeks. The FY label uses the ending year; Scintilla’s numeric YYYYWW code uses the starting year, so FY2027 W01 is 202601 in Scintilla. The 4-5-4 month pattern gives each ordinary quarter thirteen weeks. FY2025 carried the extra week in Q4, whereas FY2024 had 52 weeks. A generic NRF calendar places that insertion differently. The calendar explanation separates these labels and reporting periods.
Last verified September 6, 2026. FY2024–26 boundaries agree with the dated reporting periods in the FY25 earnings presentation. FY2027–28 dates are calculated from the same year-end rule. The corporate financial year closes January 31; use the retailer’s relevant calendar and reporting basis for invoices, forecasts, and comparisons.
TAKE THE DATES WITH YOU
The Excel workbook contains all 3 years in one filterable table with sortable dates. Each CSV contains one fiscal year, including its calculation basis, review date, and source. These are fixed reference files from the September 6, 2026 review.
The files use the same calculations as the tables below. FY2026 year boundaries are corroborated by the earnings reporting periods. FY2027–28 are rule-derived planning dates, subject to the retailer’s published schedule. Holidays are calendar dates, not shipping closures or promotion dates. Reported last-year measures can use a different week alignment.
FISCAL YEAR 2026 · WM26
Retail Reason · retailreason.com/tools/walmart-fiscal-calendar/ · Reviewed September 6, 2026. Calculated weeks; FY2026 year boundaries corroborated by Walmart earnings reporting periods. Weeks end Friday; the year ends January’s last Friday. Fiscal months follow 4-5-4. Holidays are calendar dates, not shipping closures. Boundary source: Walmart FY25 earnings presentation, linked at the reference URL above.
VERSUS FY2025
Same-numbered weeks cover calendar dates 5 to 6 days later than FY2025. 52 weeks against 53 last year, so matching week numbers spans the extra week; a reported LY measure can use a different alignment.

USE THE WEEK
The Walmart week converter turns a date into its WM week or a WM week into its Saturday-to-Friday range, and the comp week finder lines this year’s week up against last year’s.
How Walmart weeks work explains the WMYYWW format, the fiscal-month pattern, and why week 47 almost never means calendar week 47.
When a week on a scorecard shows a stopped order rather than a slow one, start with why Walmart stopped ordering your item before you touch the forecast.
