Week Numbers 2029

Adequate communication is essential in communication. In order to make accurate plans, you need to have a good overview of the months, weeks, and days to come. Often you want to make a plan based on week numbers. However, these week numbers are always hard to find.

For this issue, we provide you with this free solution: Calendar Week Numbers 2029. This Excel sheet lists all weeks in 2029. There are 52 weeks in 2029.

Unlike most years where Week 01 spills over from December of the previous year, Week 01 of 2029 starts exactly on Monday, January 1st, 2029! This makes 2029 an exceptionally clean calendar year for quarterly reporting, payroll, and fiscal planning:

Because 2029 is a standard 365-day year starting on Monday, its 52 weeks neatly cover 364 days, leaving only a single rollover day (Monday, December 31st, 2029), which initiates Week 01 of 2030.

The following week numbers are applicable in 2029:

Using this downloadable Excel spreadsheet with all week numbers guarantees you a good overview, which will save you time and efforts in the future. 

Please note that there are multiple systems for week numbering; this is the ISO week date standard (ISO-8601). Other systems use weeks starting on Sunday (US) or Saturday (Islamic). 

All weeks start on Monday and end on Sunday. 

The ISO week date system is effectively a leap-week calendar system that is part of the ISO 8601 date and time standard issued by the International Organization for Standardization (ISO) since 1988 (last revised in 2004) and, before that, it was defined in ISO (R) 2015 since 1971. It is used (mainly) in government and business for fiscal years, as well as in timekeeping. This was previously known as "Industrial date coding". 

The system specifies a week year atop the Gregorian calendar by defining a notation for ordinal weeks of the year. An ISO week-numbering year (also called ISO year informally) has 52 or 53 full weeks. That is 364 or 371 days instead of the usual 365 or 366 days. The extra week is sometimes referred to as a leap week, although ISO 8601 does not use this term.
