In the Gregorian calendar, a year consists of 12 months. Generally, each month has either 30 or 31 days, except for February, which has 28 days (29 days during leap years). There are, however, a few months with an unusual number of weeks. These are the months that have 5 weeks instead of the usual 4 weeks.
Months with 5 weeks occur when the first day of the month falls on a Sunday. This is because there are 7 days in a week, and if the month starts on a Sunday, there will be an extra day at the end of the month that doesn't fit into any of the previous weeks. This extra day creates a 5th week in the month.

5th week has only 4 days

Can happen in any month
Months with 5 weeks can happen in any month of the year, as long as the first day of the month falls on a Sunday.

Not consecutive months
Months with 5 weeks are not consecutive, meaning that they do not happen in a row. This is because the number of days in a month varies, and the day of the week that a month starts on also varies. As a result, it is not possible to have two consecutive months with 5 weeks.
- Never consecutive
Months with 5 weeks never happen in a row.
- Varying number of days in months
The number of days in a month can be 28, 29, 30, or 31. This variation in the number of days can affect whether or not a month has 5 weeks.
- Varying day of the week that months start on
The day of the week that a month starts on can also affect whether or not it has 5 weeks. For example, a month that starts on a Sunday is more likely to have 5 weeks than a month that starts on a Monday.
- Can be separated by one or more months
Months with 5 weeks can be separated by one or more months that have 4 weeks.
For example, in the year 2023, January has 5 weeks, but February, March, and April all have 4 weeks. The next month with 5 weeks is May. This shows that months with 5 weeks are not consecutive and can be separated by months with 4 weeks.
More common in some years
Months with 5 weeks are more common in some years than in others. This is because the number of months with 5 weeks in a year depends on the day of the week that January 1st falls on. If January 1st falls on a Sunday, there will be 4 months with 5 weeks in that year. If January 1st falls on a Monday, there will be 3 months with 5 weeks. In all other cases, there will be 2 months with 5 weeks.
- Years with 4 months of 5 weeks
In years when January 1st falls on a Sunday, there will be 4 months with 5 weeks: January, April, July, and October.
- Years with 3 months of 5 weeks
In years when January 1st falls on a Monday, there will be 3 months with 5 weeks: April, July, and October.
- Years with 2 months of 5 weeks
In all other years, there will be 2 months with 5 weeks. These months can be any combination of January, April, July, and October, depending on the day of the week that January 1st falls on.
- Pattern repeats every 28 years
The pattern of months with 5 weeks repeats itself every 28 years. This means that the same sequence of months with 5 weeks will occur again in 28 years.
For example, in the year 2023, there are 2 months with 5 weeks: January and October. In the year 2024, there will also be 2 months with 5 weeks, but they will be April and July. This is because January 1st falls on a Monday in 2024, which means that there will be 3 months with 5 weeks in that year. The pattern of months with 5 weeks will continue to repeat itself every 28 years.
Affect scheduling and planning
Months with 5 weeks can affect scheduling and planning, as they can disrupt the usual 4-week pattern of the month. This can be especially challenging for businesses and organizations that have regular schedules or deadlines.
- Disrupt regular schedules
The shorter 5th week can disrupt regular schedules, as it may require special arrangements to accommodate the fewer number of days.
- Adjust deadlines and timelines
Businesses and organizations may need to adjust deadlines and timelines to accommodate the shorter 5th week.
- Impact project planning
Project plans may need to be revised to account for the shorter 5th week, which can affect project timelines and resource allocation.
- Challenges for payroll and billing
Months with 5 weeks can also present challenges for payroll and billing, as some systems may not be able to accommodate the extra day.
For example, a business that pays its employees on a weekly basis may need to make special arrangements to pay them for the extra day in a month with 5 weeks. Similarly, companies that bill their customers on a monthly basis may need to adjust their billing cycles to accommodate the shorter 5th week.
Overall, months with 5 weeks can introduce some challenges for scheduling and planning, but with careful planning and adjustments, these challenges can be overcome.
Create unique calendar patterns
Months with 5 weeks can create unique calendar patterns, especially when two 5-week months occur in a row. This can disrupt the usual rhythm of the calendar and create interesting visual patterns.
- Back-to-back 5-week months
When two 5-week months occur in a row, it creates a unique calendar pattern with 10 weeks in a row. This can be visually striking and can disrupt the usual flow of the calendar.
- Irregular чередование 4- and 5-week months
The чередование of 4- and 5-week months can also create unique calendar patterns. For example, in a year with 4 months of 5 weeks, there will be a чередование of 5-week and 4-week months throughout the year.
- Asymmetrical quarters
Months with 5 weeks can also create asymmetrical quarters. For example, in a year with 4 months of 5 weeks, the first and third quarters will have 13 weeks each, while the second and fourth quarters will have 12 weeks each.
- Unique holiday patterns
Months with 5 weeks can also affect the patterns of holidays that fall on specific days of the week. For example, if a holiday always falls on a Monday, it may fall on a different date in a year with a 5-week February compared to a year with a 4-week February.
