# Date Calculation Formula - Determine Longer Period Of Time

Aug 9, 2012
How to create a formula to determine the longer period of time between two date calculations and enter the longer period of time in the cell.

My Spreadsheet:

Cell M2: Birthdate (entered in cell as 11/1/2004)

Cell J2: Last date of service (entered in cell as 10/31/2011)

Cell G2: Calculation to enter the longer period of time between (M2 (year) + 21) and (J2 (year) + 7)

Example using information from above:

2004 + 21 = 2025

2011 + 7 = 2018

2025 is the result I want added to G2

If there is any way to include the month/year in G2 that would be ideal.

I'm working on a dynamic payroll spreadsheet that will automatically calculate the overtime worked in a week. Right now, I'm running into a snag. My issue is with the formula in Column R. Right now, as shown below, it is doing the calculation based on regular hours minus 40 to determine the OT time. The snag is very messy and it lay in this: while the row by row calculations for total overtime worked for the week is correct, the sum at the bottom is very much off. I need an accurate method to sum the hours of overtime for the given column.

Here are the guidelines for the pay periods and overtime:

1. The pay periods for the month go from the 1st to the 15th and the 16th to EOM (End of Month). This means that the pay period could end on any given day of the week. More on this in a moment.

2. A work week is defined as Sunday to Saturday.

3. Overtime is calculated based on the rule of anything over 40 hours in a given work week.

4. Holiday hours worked do not count towards the 40 hour mark in granting overtime since Holiday pay is automatically overtime.

If it were just a matter of a bi-weekly (every 2 weeks) pay period, I would simply state =IF(weekday(DATE)=7,Hours_Worked - 40,0), and tag a SUM(range) at the bottom. Unfortunately, with it being a semi-monthly (twice a month), the end of the pay period could be a Wednesday, so a reference to day of the week won't work unless the formula can dynamically determine which set of data to evaluate.

I'm completely willing to toss out the current method of determining overtime. This is the calculations sheet that references a cleanly formatted and designed time card on a tab called "Time Card", so this isn't the full workbook. In fact, once the whole thing is done, this calculation sheet will be hidden.

Columns M and N (which are formula referenced in Column P) are basic End - Start calculations and were hidden to simplify the display as well as the number of formulas displayed.

Column L (formula referenced) is a Yes/No display for if the date in question is holiday pay.

I need to determine a formula which will allow me to calculate a future date based upon a current date with varying time periods.

For example:

I have a bill which is paid on the 15th and last business day of each month. I would like to be able to see the next due date regardless of what day of the week it is.

I have a bill which is paid every other Tuesday. I would like to know the next due date without having to enter +14 for every due date in the future. In other words, it is preferable to be able to open the spreadsheet and automatically see the next due date, not use autofill to repeatedly add +14 to a previous date which would limit the # of future due dates that could be calculated.

I have a bill which is paid on the last business day of each month, not the last Friday of each month. I would need excel to return a value for the last day of the month which = Monday-Friday, regardless of what day of the week it may be as long as it isn't Saturday or Sunday(holiday exclusion would be nice but not required).

I have a spread sheet with 4 columns x 20,000+ rows running this forumla

=IF(FALSE=ISERROR(VLOOKUP($G2,$B:$B,1,0)),$G2,$H3)

The formula works perfect - the only problem is the calc times can take 10+ minutes ( and longer with larger data sets ) because the data sets are so large. Is there another formula or way to get the same result that would speed the process up?

I have found an older thread that explains how to determine if a date falls in DST or not. See here Daylight Savings Time Funcitions. It does not follow the DST rules we use here in Canada and the formula is very confusing to me as it uses arrays, something I have yet to fully understand. DST in Canada begins the 2nd Sunday of March and ends on the 1st Sunday in November. I have a date in one column and a time in the next. What I would like to do is have a formula that checks to see if the date falls in DST and if so adds 1 hour to the second column. The result will show up in a third column.

What calculation would I enter in a results cell if I wanted to find the delta between 2 times in date format that repersent just the business hours of 8am-5pm, therefore excluding after hours and weekends.

eg.

Date 1 Date 2 Result Time

23/07/07 8:00 24/07/07 14:55 15:55

So far I can't get the caluclation that will compensate for the after hours and week ends.

I am trying to calculate the response time between when a phone call comes into my workplace and when the responder calls back...I have created a formula that does this using the times and dates of when the calls were recieved and went back out. This works except when the call comes in on one day and goes back later in the day the next day, making the response time larger than 24 hours. I also have it set up to eliminate 15 and a half hours from the calculation because our place of business is not open during this time. Further details....

The formula currently being used is... =IF(G50=E50, H50-F50+(H50

I am attempting to pick up a date with time entry on a worksheet and place it into a TextBox on a UserForm. Format on the sheet is mm/dd/yyyy h:mm AM/PM. The UserForm is placing the value as mm/dd/yyyy 12:00 AM. here is the

Private Sub UserForm_Initialize()

If Not Range("dDate").Value = "" Then

TextBox2.Value = Range("dDate").Value

TextBox2.Text = Format(DateValue(TextBox2.Text), "mm/dd/yy h:mm AM/PM")

Else

TextBox2.Value = ""

TextBox2.SetFocus

End If

End Sub

"dDate" is the named range where the date is sitting. The format is also set on the TextBox2 exit event. Can anyone see why only the date portion is being transfered with the default 12:00 AM for no time component of the value?

I have a protected worksheet. Users wish to be able to track changes in the input cells. The suggested approach for this is to temporarily disable sheet protection and allow them to change the font color, then protect afterwards. What I would like to do is:

i) check whether they are in an input cell

ii) if so, then prompt the user with the 'Font Color' dialog box

iii) apply the font color selected to the input cell

I'm struggling to find the dialog box I need. I can launch the one to change the interior color, no problem (Application.Dialogs(xlDialogPatterns).Show). But that's no use to me, I just want a color palette that specifically relates to the Font Color

I have thousands of timestamps that have a start & end date and time in 2 separate columns. (one named start and one named end...)

I also have numerous set time periods that i'm interested in.. (about a dozen or so)

for example 01/01/2008 - 05/01/2008, 07:30:00 - 10:00:00

What i need is to be able to count the number of times the full time period i am interested (07:30:00 - 10:00:00) in falls in between the thousands of start and end timestamps i have. The time periods must also fall within the date range specifed.

So if my timestamps were

Start: 01/01/2008 06:30:00 & End: 02/01/2008 11:00:00, based on the set time period above, there would be a count of 2

and if my timestamps were

Start: 01/01/2008 07:05:00 & End: 02/01/2008 09:00:00 there would be a count of zero as there is not a full uninterupted timeperiod 07:00:00 - 10:00:00 between these timestamps.

and if my timestamps were:

Start 01/01/2007 07:00:00 & End 02/01/2007 10:00:00 the count would be zer as this is a year early!

I want to return a value based on once off time related data which is captured at 4 time periods throughout a day. I have another set of data which does not line up with this data but I want it to return the value closest earliest value.

Given this data:

27-6-14 3:00 12

27-6-14 7:00 18

27-6-14 11:00 19

If I have a time like 27-6-14 5:00 I want to return a value of 12 (Previous time). How would this be possible?

I am looking for a single formula I can run along a single row that looks at several columns of data, and then checks if the date range falls between the running row, take it's relevant number, and multiply it by a single rate. The attached probably explains it clearly - I think the solution would be some sort of Sumproduct, but my attempts have failed!Example - Date Range with Calculation.xlsx

I'm needing a formula that will determine the number of days that fall in a specific month based on a date range. For example, if I have a date range of 10/15/2009 to 01/13/2009, I need the formula to determine the number of days in each month within the range (October has 15 days in the date range; November has 30, December has 31, and January has 13.) I have a large spreadsheet that would be so much easier to manage with such a formula. Currently, my spreadsheet is setup as follows. I need the forumla automatically fill in the number of days under each month.

I have Three different combinations which are in cell A & B, These combinations are with similar signs as in A1=2- & B1 = 2- (& A1 = 2+, B1=2+). Then I have numbers with no signs which A1 =2 B1= 2. My approach is to limit to these and these combinations only and use a formula which is uniformally applied on these combination. I want A1 and B1 to take only like signs like -- or ++ or without any sign. The rest shd be ignored. IS there a way of sorting two columns which have different combinations liek -- or ++ or -+ into a area where u can apply a particular formula? Hence first i take a number and move signs on the left and then apply this

IF A7 = 2- . B7 = 3- THEN

IF(OR(RIGHT(TRIM(B7),1)="-",RIGHT(TRIM(B7),1)=" ",RIGHT(TRIM(B7),1)="+"),LEFT(TRIM(B7),LEN(TRIM(B7))-1)*3,B7*3)

=IPMT(4.3%/12,3,5*12,-7000)/(4.3%/12)

What i would like to do is for the period to be self calcuating from current date and the loan start date. I can return a value in days using start date - today() and aware month function returns the month number but stuggling to find a way to work out cumulative month from the start date.

Calculate certain time increments for various work-shifts. I have a start time,finish time and increments of time across the spectrum of 24 hours. There are also multiple start time across the 24 hour period with some start times begining on one day and ending on the next day.

Example

In B5 Startime is 22:00

In C5 Finishtime is 06:30

In I3 increment begins at 00:00

In I4 increment ends at 00:30

The employee working the shift from 22:00 - 06:30 would fall into the time increment of 00:00 - 00:30 where another employee working a different shift (08:30 - 17:00) would not. I'm looking for a formula that would return a 1 in a cell if the employee fell into the 00:00 - 00:30 time increment and a 0 in a cell in the employee did not fall into the time increment.
