Week 30, 2023

Week 30 of 2023

ISO week 30 of 2023 (2023-W30) runs Monday, July 24, 2023 through Sunday, July 30, 2023. The full range is Jul 24 – Jul 30, 2023. Days follow the ISO Monday–Sunday convention. The US week label for dates in this window is 30–31.

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 legal calendar date alone.

ISO vs US week labels

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 on week pages so you can match internal reports that use either system. When the two disagree at year boundaries, the cross-year note on this page explains which label applies to each calendar day.

Day-by-day breakdown

The grid above lists all seven days with weekday names, calendar dates, and day-of-year numbers. That layout helps compare ISO week boundaries against month-end billing cycles or school weeks that start on Sunday. Each row links back to the parent year table for context. Payroll teams often map ISO weeks to pay periods even when checks are issued on a different weekday schedule.
