This article explores the limitations of the DateTime type in C# when creating scheduled tasks that only require month and day components, and presents solutions to address these challenges. By analyzing the inherent characteristics of DateTime, we propose two main approaches: ignoring the year and using the current year to create DateTime objects, or implementing a custom MonthDay struct to precisely represent dates without years. The article details the design of the MonthDay struct, including constructors, implementation of the AddDays method, and considerations for edge cases such as leap years. Additionally, we discuss how to choose the appropriate method based on practical needs, providing complete code examples and best practice recommendations.
