I'm seeking a way to get all American holidays as an array of NSDates. Is there a way to implement that?

How many American public holidays are there?

The Federal Government recognizes 10 holidays. However, several things can affect when you observe your holidays such as your alternative work schedule (if you work one) and if you work full time or part-time.

Is October 10 2022 a holiday in USA?

Columbus Day takes place on the second Monday of October. It is a federal holiday, so most banks and government offices are closed.

If you only want US federal Holidays, I wrote this method. You could use these techniques to calculate any holiday though.

-(NSArray *)getUSHolidyas{
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    formatter.dateFormat = @"yyyy";

    NSString *year = [formatter stringFromDate:[NSDate date]];
    formatter.dateFormat = @"M/d/yyyy";

    //Constant Holidays
    NSDate *newYearsDay = [formatter dateFromString:[NSString stringWithFormat:@"1/1/%@",year]]; //Use next year for the case where we are adding days near end of december.
    NSDate *indDay = [formatter dateFromString:[NSString stringWithFormat:@"7/4/%@",year]];
    NSDate *vetDay = [formatter dateFromString:[NSString stringWithFormat:@"11/11/%@",year]];
    NSDate *xmasDay = [formatter dateFromString:[NSString stringWithFormat:@"12/25/%@",year]];

    //Variable Holidays
    NSInteger currentYearInt = [[[NSCalendar currentCalendar]
                                 components:NSYearCalendarUnit fromDate:[NSDate date]] year];

    NSDate *mlkDay = [self getTheNth:3 occurrenceOfDay:2 inMonth:1 forYear:currentYearInt];
    NSDate *presDay = [self getTheNth:3 occurrenceOfDay:2 inMonth:2 forYear:currentYearInt];
    NSDate *memDay = [self getTheNth:5 occurrenceOfDay:2 inMonth:5 forYear:currentYearInt]; // Let's see if there are 5 Mondays in May
    NSInteger month = [[[NSCalendar currentCalendar] components:NSYearCalendarUnit fromDate:memDay] month];
    if (month > 5) { //Check that we are still in May
        memDay = [self getTheNth:4 occurrenceOfDay:2 inMonth:5 forYear:currentYearInt];
    NSDate *labDay = [self getTheNth:1 occurrenceOfDay:2 inMonth:9 forYear:currentYearInt];
    NSDate *colDay = [self getTheNth:2 occurrenceOfDay:2 inMonth:10 forYear:currentYearInt];
    NSDate *thanksDay = [self getTheNth:4 occurrenceOfDay:5 inMonth:11 forYear:currentYearInt];

    return @[newYearsDay,mlkDay,presDay,memDay,indDay,labDay,colDay,vetDay,thanksDay,xmasDay];

-(NSDate *)getTheNth:(NSInteger)n occurrenceOfDay:(NSInteger)day inMonth:(NSInteger)month forYear:(NSInteger)year{

    NSDateComponents *dateComponents = [[NSDateComponents alloc] init];

    dateComponents.year = year;
    dateComponents.month = month;
    dateComponents.weekday = day; // sunday is 1, monday is 2, ...
    dateComponents.weekdayOrdinal = n; // this means, the first of whatever weekday you specified
    return [[NSCalendar currentCalendar] dateFromComponents:dateComponents];

  • Here you'll find RSS-feeds with the holidays. It doesn't list year, but in the docs you'll find information how to change date ranges.
  • Download it. I would suggest ASIHTTPRequest for that task.
    parse the RSS-feed. you can do so by normal XML-parsing, or you use a specialized parser. MWFeedParser would be one option.
  • Save the dates. either by using CoreData, or Event Kit Framework
