Week 1 in 2025 officially begins on Monday, December 30, 2024, and concludes on Sunday, January 5, 2025.
Understanding how week numbers are assigned, especially at the turn of a new year, can sometimes lead to unexpected dates for the first week. According to common international standards, Week 1 is typically defined as the first week of the year that contains at least four days of that year. This often means that Week 1 may start in the preceding calendar year, as is the case for 2025.
This system ensures that every week consists of seven days and that week numbers progress sequentially throughout the year without breaks or partial weeks. It's a standard approach that helps maintain consistency in scheduling and planning across various industries and applications.
Here are the precise dates for Week 1 of 2025:
| Week Number | From Date | To Date |
|---|---|---|
| Week 01 | Dec. 30, 2024 | Jan. 5, 2025 |
This consistent week numbering system is widely utilized for project management, financial reporting, academic calendars, and other scenarios where a standardized weekly structure is beneficial.
