A C# library extending System.DateTime with working day calculations, holiday support, and natural language date differences for multiple cultures.
DateTimeExtensions is a C# library that extends the functionality of System.DateTime and System.DateTimeOffset with practical methods for date and time operations. It solves common problems like calculating working days, handling holidays across cultures, and generating natural language date differences, making date manipulation more intuitive and less error-prone.
C# developers working on applications that require complex date calculations, such as scheduling systems, payroll software, or international business applications with regional holiday considerations.
Developers choose DateTimeExtensions for its comprehensive, culture-aware date operations out of the box, reducing the need to write custom logic for working days, holidays, and date differences while maintaining clean, expressive code.
This project is a merge of several common DateTime operations on the form of extensions to System.DateTime, including natural date difference text (precise and human rounded), holidays and working days calculations on several culture locales.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Includes predefined holiday definitions for multiple cultures like en-US and de-DE, as listed in the README, eliminating the need to manually source regional holiday data.
Generates human-readable text for date gaps using ToNaturalText(), making UI displays more user-friendly without custom formatting logic.
Simplifies adding or subtracting working days with AddWorkingDays(), automatically accounting for weekends and holidays based on culture settings.
Exports holidays to formats like Office Holidays via ExportHolidayFormatLocator, easing integration with external scheduling systems.
Allows implementing IWorkingDayCultureInfo for bespoke working day rules, adapting to specific business needs beyond predefined cultures.
The README acknowledges missing cultures and relies on community contributions, which can be a barrier for applications in niche or unsupported regions.
Extends System.DateTime, which is mutable and not thread-safe, conflicting with modern C# best practices that favor immutable types like DateTimeOffset.
While an official documentation link is provided, the README lacks detailed examples for advanced features like custom exporters, forcing developers to explore source code.
Adds library dependency and processing layers for simple operations that could be done with built-in .NET methods, potentially impacting performance in high-volume scenarios.
