No AI, just math.

Efficient Date Recurrence Library for .NET

DateRecurrenceR is a .NET library designed to handle and manage recurrence date patterns efficiently.

Key Features

  • Dynamic Subrange Generation: Generate only the needed dates within a specified range, optimizing performance and memory usage.
  • Time Localization Simplification: Uses DateOnly, eliminating issues related to time localization.
  • Flexible Collection Handling: Returns an enumerator, allowing developers to choose the collection type.
  • Optimal Performance: Boasts a Big O notation of O(1), ensuring efficient operations.

Methods for Recurrences

method description
Daily Gets a daily recurrence by interval
Weekly Gets a weekly recurrence by days of week and interval
Monthly Gets a monthly recurrence by days of week or day of month and interval
Yearly Gets an yearly recurrence by days of week or day of month or day of year and interval

All these methods return an instance of IEnumerator<DateOnly>.

All parameters

parameter description
beginDate The date when the recurrence begins.
endDate The date when the recurrence ends.
interval The interval between occurrences.
fromDate The date when a specific range starts.
toDate The date when a specific range finishes.
count The maximum number of contiguous dates.
dayOfWeek The day of the week.
dayOfMonth The day of the month. Takes the last day of the month if dayOfMonth is more than the days in the month.
dayOfYear The day of the year.
weekDays Days of the week.
indexOfDay Index of dayOfWeek in the month.
numberOfMonth The number of the month.
firstDayOfWeek The first day of the week.

Subranges

All methods for recurrences support the following subrange rules:

By dates
  • Parameters: fromDate and toDate
  • Rule: Takes dates from the intersection [beginDate, endDate] ∪ [fromDate, toDate]
By count
  • Parameters: fromDate and count
  • Rule: Takes dates from the intersection [beginDate, endDate] ∪ [fromDate, DateOnly.MaxValue] and takes the first count dates

Examples of Use

var enumerator = Recurrence.Daily(beginDate, endDate, fromDate, toDate, interval); // IEnumerator<DateOnly>
