Excel function to create due dates that land on a business day - excel

I'm stuck creating a formula that will calculate days before the end of the month then adjust to make sure it is a business day. For example: 30 days before 6/30/2015 is 5/31/2015 which is a Sunday. I need that to adjust to the Friday before.
I'm working on finding the due dates of a number of documents that are due a certain number of days before another date. For example: documents are due 30 days before the last day of the month. However, the number of days varies and the due date needs to fall on a business day (Monday-Friday). Sometimes it's 30 days, sometimes it's 60 days, sometimes it's 30 calendar days + 5 business days, etc.
I've been able to calculate 30 days + 5 business days with the following formula:
=workday(start_date-30,-5)
Any ideas how to adjust this so that I can just have the due date be 30 calendar days before a certain date but also always be a business day?

Using WORKDAY you can use a formula like this:
=WORKDAY(A1+B1+1,-1)
where A1 is your start date and B1 the number of days to add.

You probably need to write a macro function or maybe some nested IF statements in your cell's formula.
Take a look at http://www.mrexcel.com/forum/excel-questions/481558-round-date-nearest-workday.html
That solution moves forward to the nearest workday, but the principle is sound: just subtract instead of add.

How to calculate accumulated vacation days in Excel based on days (and hours) worked per month?

TLDR: I need a way to track date values in a dynamic calendar and count the days I've worked on on a monthly base.
So I've made a dynamic calendar (in the 1904 Date system to enable negative time handling) to help me track days and hours worked in Excel that has some automatic features. I would now like to add a calculator to calculate the accumulation of vacation days based on the following conditions:
Days worked per month >= 14
OR
The total hours worked per month >= 35
If one or both of these conditions are met I will receive 2 vacation days (2.5 after the 1st year of employment) and the accumulated vacation days should be shown in a single cell C7 (see picture for reference).
I know that I need to calculate the days that I've worked on on a monthly base and compare the result to the 1st condition (and the same for the worked hours and compare the result to the 2nd condition, but the solution for that is much the same as for the 1st condition). I've made my calendar in a way that I can't use fixed cells to do the calculation, as the length of the calendar is fixed to 53 full weeks and the dates change to accommodate the length according to the year in cell C2 i.e. January 1st will not always be in cell D17. Here are the first 10 rows of my dynamic calendar in Table Markdown format with the formulas as asked.

=XLOOKUP(D11;_1pyhapaivat3[Start Date];_1pyhapaivat3[Subject];"")

I've tried combining the DATE and SUM functions with other functions like COUNTA, and COUNTIF. I've also tried using different LOOKUP functions but to no avail.

Calculate annual leave between two dates in Excel

This task seems easy enough yet I just can't figure a way of doing this without resorting to vba.
All I need is to know the number of hours an employee has used up on annual leave, based on a start and end date, and their hours of work.
To be more clear, this example shows one employees contracted hours from Monday to Sunday i.e. they work only Weds, Thurs, and Friday, for 7.5 hours each day.
Below shows the start and end date that the employee has chosen to take for annual leave. I need to calculate, based on their contracted hours, how much annual leave is used between the two dates. The answer would be 45 hours in this case.
Here's another approach - I've expanded the days between the start and end dates into an array then used the resulting day numbers to offset into the days of work range
=SUMPRODUCT(N(OFFSET(A3,0,WEEKDAY(ROW(INDIRECT(A6&":"&B6)),2)-1)))
If you had a list of holiday dates somewhere (say in I3:N3) you could exclude them as follows
=SUMPRODUCT(N(OFFSET(A3,0,WEEKDAY(ROW(INDIRECT(A6&":"&B6)),2)-1))*ISNA(MATCH(ROW(INDIRECT(A6&":"&B6)),I3:N3,0)))
- it is a bit long-winded but the only way I can think of at the moment.

How do I calculate a date by adding 30 calendar days, where end date must be business day?

I'm wondering if this is possible. I am creating a spreadsheet to track project due dates. Each project must be completed by the 30th calendar day, but must be turned in on a business day.
Currently, I am just adding 30 days to the start date but this means some due dates aren't always accurate. For example, if the 30th day is Saturday, April 2nd, then the real due date would be Friday April 1st.
Is there a way to construct a conditional such that the due date equals the 30th calendar day, unless that falls on a weekend / holiday, where it then falls on the next earliest business day?
I've been struggling to figure out a way to do this.
For English settings in Excel, with a date in A1, in B1 enter:
=IF(TEXT(A1+30,"DDDD")="Sunday",A1+28,IF(TEXT(A1+30,"DDDD")="Saturday",A1+29,A1+30))
This simple-minded approach only handles Saturdays and Sundays, not arbitrary holidays.
I would prefer more elegant way like using WORKDAY.INTL
=WORKDAY.INTL(A2+31,-1,1,E2:E)
Explanation: start date + 31 days (1 day more than maximum calendar days)
then subtract 1 working day - going to last previous working day
Reason: because this formula does know when are weekends (by using variables) and also knows to skip hollydays by a custom list.
here is an example sheet you can use
Revised after comment:
Try this:
=(A4+30)+CHOOSE(WEEKDAY(A4+30),1,0,0,0,0,0,-1)
Your date, in A4, + 30 days, then add an amount of days until the next workday. If A4 + 30 is a Saturday it will subtract 1 day, a Sunday will add 1.

Excel Subtracting periods from specific dates using 360-day calendar?

Got formulas for figuring my differences between date periods in days as follows:
=IF(F7="","0",DAYS360(F6,F7)+1)
This gives the days result for each period that I am interested in, but I then need to add each period of days together and subtract them from a current date (like doing service computation). The issue is that I need to do this second calculation within a 360-day calendar as well. If I just try to do a days360() formula with one value being the current date and the other being the total number of days that I need to backtrack, then the "original" date that it comes up with is drastically off.
This seems to be the equivalent of the difference between NETWORKDAYS and WORKDAY functions. The former counts working days between two dates, the latter adds working days to a date, you essentially want the WORKDAY equivalent for DAYS360, which I don't think exists.
You can manipulate DAYS360, though, e.g. with a date in A2 and number of days to subtract (in 360 day mode) in B2 you can use this formula for the date
=A2-B2-MATCH(B2,INDEX(DAYS360(A2-B2-ROW(INDIRECT("1:"&CEILING(B2/30,1))),A2),0),0)

Elapsed Days Hours Minutes Excluding Weekends and Holidays Time

This sounds simple but I have been pulling my hair out trying to figure out a solution. Any help before I go bald would be great.
I need a formula which is able to
calculate the duration in (days, hrs, mins) between two date\time values (eg 05/12/2012 5:30 PM and say 07/12/2012 5:45 PM);
excluding weekends and holidays.
I would like the result of the formula to read as follows "e.g 2 Days 0 Hrs and 15 Mins".
Thanks

You can use NETWORKDAYS and NETWORKDAYS.INTL to achieve this
A bit of manipulation is required as these return net whole days:
Use these functions to calculate the number of non workdays, then subtract from the difference between start and end dates
=E3-D3-(NETWORKDAYS.INTL(D3,E3,"0000000")-NETWORKDAYS(D3,E3,$A$16:$A$24))
This returns the working day difference, where 1.0 = 1 day
NETWORKDAYS.INTL(D3,E3,"0000000") calculates whole days between the two dates (no weekends, no holidays)
NETWORKDAYS(D3,E3,"0000000",$A$16:$A$24) calculates whole working days days between the two dates (Sat/Sun weekends, holidays as per your list in $A$16:$A$24)
Difference in non-working days between the two dates.
E3-D3 is time between start and end date/times (1.0 = 1 day)
Use custom number formatting to display thye result in the format you require
d "Days" h "Hours" mm "Mins"
Note: this format won't work for negative values, you will need an alternative for when end date is before start date.
The following formula works like a treat with no additional formatting or manipulation.
To make it more stable I have turned all the holiday dates for UK 2012/13 into ‘Excel Serial Number’ format and placed them in an array bracket.
Replacing the "D5" in the formula with your cell reference for your course or metric "End Date" and "E5" with your course or Metric for "Completion Date".
=IF(E5<D5,"-"&TEXT(D5-E5,"h:mm"),NETWORKDAYS(D5,E5,({40910,41005,41008,41036,41064,41065,41148,41268,41269,41275,41362,41365,41400,41421,41512,41633,41634}))-1-(MOD(E5,1)<MOD(D5,1))&" days "&TEXT(E5-D5,"h:mm"))
