How to use this calculator
Choose the calendar year containing the closing anchor, its month/day, week start, closing rule and period pattern. Select how to compare weeks after a 53-week year.
The year runs from the day after the previous closing date through the current closing date. The extra week belongs to period 12. Same-numbered comparisons and the optional one-week restatement are explicit; a week with no prior equivalent is reported.
A worked example
With a January 31, 2027 closing anchor, Sunday week start and nearest-week-end rule, the year runs February 1, 2026 through January 30, 2027: 52 weeks. A January 31, 2029 anchor produces 53 weeks.
Is this every retailer's official fiscal calendar?
No. Retailers may use other anchors, patterns or comparison policies. Match your organization's rules. The default Sunday/January 31 convention follows the familiar NRF-style calendar, while the year label here names the closing anchor year.
Further reading: NRF 4-5-4 calendar and 53-week guidance. Your entered rules determine this result.
Which calendar and years are supported?
Use Gregorian dates from 1900 through 2100, with results in that range. Most daily plans allow up to 366 dates; service-budget searches allow 731. Timed intervals have exclusive ends and use browser IANA time-zone rules; nonexistent local times are rejected and repeated times require your choice. Working calendars and policy terms are entered by you. The holiday comparison uses TimeCubby's published country/region coverage. Copy, CSV and print include assumptions; calendar exports appear when dated events exist.
What happens to my dates?
Calculations run on your device. Saving a calculation is optional and keeps it in this browser. A setup link contains the dates and settings you entered; anyone with the link can read them. Use one tab per saved calculator. Clear saved data from Privacy & settings.
