How to get the next working date?

Question

Hi,
I need to extract data between the 2nd of the month, and second working date of the following month.
Here is the code I have to check if the date is a weekend, and check if it is in the Holidays table (for UK Holidays):
(This code is to check against Easter 2014, so Good Friday was on the 18th of April, Easter Monday was on the 21st, and the date I want returned is Tuesday the 22nd but I cannot get it working correctly).
declare @LatestDate datetime
set @LatestDate = DATEADD(m,-9,getdate()) -- cast('01/11/2014' as datetime) --dateadd(m,1,datediff(d,0,'01/11/2014'))
set @LatestDate = DATEADD(d,13,@LatestDate)
print @LatestDate
if datepart(dw,@LatestDate) in (1,7)
Begin
while datepart(dw,@LatestDate) in (1,7)
OR
exists (select * from Hermes_Rep..Holidays where Holiday =right(CONVERT(CHAR(10), @LatestDate, 101),4) + '-' + left(CONVERT(CHAR(15), @LatestDate, 101),2) + '-' + SUBSTRING(CONVERT(CHAR(15), @LatestDate, 101),4,2))
Begin
set @LatestDate=DATEADD(d,1,@LatestDate)
End
End
What I need is for my code to always return the 2nd working day of any month, taking into account weekends, and Holidays in the Holidays table.
The Holidays table has dates in the format '2014-04-18 00:00:00' (for Good Friday 2014)

Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI-ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI-ISO Standard SQL. And you need to read and download the PDF for:

Do you know what a calendar table is?

Catholic or Orthodox Easter?  This is one of many reasons we do not use computations in SQL. What you did is the wrong approach  done with bad programming. For example, we do not use the old Sybase getdate() now. The only display format allowed in
ANSI/ISO Standard SQL, but you used a local dialect! 
COBOL treats dates as strings like you did; SQL has a temporal data type.

The idea of a Holiday table is bad; why are these dates totally different entities from other dates? Would you split Personnel on sex and have “Male_Personnel” and “Female_Personnel”? 
The Julian business day is a good trick. Number the days from whenever your calendar starts and repeat a number for a weekend or company holiday.
CREATE TABLE Calendar
(cal_date DATE NOT NULL PRIMARY KEY, 
 julian_business_nbr INTEGER NOT NULL, 
INSERT INTO Calendar 
VALUES ('2007-04-05', 42), 
 ('2007-04-06', 43), -- good Friday 
 ('2007-04-07', 43), 
 ('2007-04-08', 43), -- Easter Sunday 
 ('2007-04-09', 44), 
 ('2007-04-10', 45); --Tuesday
To compute the business days from Thursday of this week to next
 Tuesdays:
SELECT (C2.julian_business_nbr - C1.julian_business_nbr)
  FROM Calendar AS C1, Calendar AS C2
 WHERE C1.cal_date = '2007-04-05',
   AND C2.cal_date = '2007-04-10';
