I have cells with date values formatted as DD/MM/YYYY. What I need is to use that value to determine the number of years that have passed since that date as of Jan 1st of the current year.
For example.
4-4-2010 - the value I should see is 3 since only 3 years had passed as of Jan 1st 2014.
But when I open the spreadsheet next year on Jan 2nd it should show 4 since another year will have passed.
I don't need to see months or any increments of years. Just a whole number.
DD/MM/YYYY isn't really supported as a date format by Google Sheets (at least from what I've seen, correct me if I'm wrong. How can you identify if something is DD/MM/YYYY or MM/DD/YYYY when neither DD or MM is > 12?). But since all you're trying to do is get the number of years since a certain year, all you have to do is extract the year from the cell you're looking at and subtract that from the current year.
Assuming the date you using is in cell A1:
=year(now()) - year(A1)

My client wants to work in Nepal's Official Calendar- Hindu Calendar (Vikram Sambat). Currently i am using JQuery Ui selector which is static one. In application I need to find the number of days between two dates which are in Vikram Sambat Format; Now, I need to convert Nepali date to English and find the number of days.
And most awkward thing is, general convention of converting date
algorithm could not work perfectly for too old dates like 1960's and
upcoming dates.
By tallying I found that with in 60 years there were only 14 leap years in Vikram Sambat format, actually there must 15 leap years according english date, and number of days in a month also varying year to year some time having 31 some time 32.
I don't want to make use of array for this purpose, i want to know the logic that could determine the number of days in a month.
One of the general convention is Nepali Date to English Date: Subtract - 56 Years - 8 Months - 16 Days
I would like a spreadsheet row to contain the date of today, but only on every other Thursday, changing at 9:30 am.
To give you an example:
Next thursday the 21.07.16 it shell contain "21.07.16".
Until in exactly 14 days on thursday the 4.08.16 it shell contain this date and than change to 4.08.16.
Also I would like this change to happen at 9:30 am.
I can not think of a way how to do this. Can you point me into a direction?
One has to set a starting datetime somewhere in the past, such as July 7, 2016, at 9:30am.
Then find the difference between the current and the starting datetime. Truncate this difference down to a multiple of 14, and add this value to the starting datetime.
The datetimes are represented in Sheets numerically as the number of days since December 30, 1899. In this system, 2016-07-07 9:30 is about 42558.4 So the formula would be
=42558.4 + 14*floor((now()-42558.4)/14)
The output should be formatted as a date.
A less cryptic version is
=value("2016-07-07 09:30") + 14*floor((now() - value("2016-07-07 09:30"))/14)
(value follows the local convention for parsing dates, but I hope the format I used will be understood universally.)
What date time format is this : 735715:37344280
<ExecDateTOD Friendly="Monday April 27, 2015 10:23:00am">735715:37344280</ExecDateTOD>
It's found in C:\Windows\Performance\WinSAT\DataStore\file_name.xml, and is the date time when the Windows Experience Index Assessment test was run.
Any idea how it's structured and can be edited? I need to change it to a previous years Date.
It seems that this format is called VariantTime, in MSDN the call to convert time is called VariantTimeToSystemTime. So it may be number of days, with decimal part after the :.
For the timestamp 735715:37344280
The first number (the one before the colon) is the number of days since the year 0:
735715 / 365 = 2015.66
The second number (the one after the colon) is the number of milliseconds that have passed within the current day.
37344280 / (1000*60*60) = 10.37 hours since start of day
So you can just subtract 365 days from the first number to obtain the previous year like this:
<ExecDateTOD Friendly="Monday April 27, 2014 10:23:00am">735350:37344280</ExecDateTOD>
Note that there were no leap years in either 2015 or 2014, so these year are exactly 365 days long.
Here is a link to a page with another <ExecDateTOD> tag where you can compare: http://www.scribd.com/doc/82935159/2012-01-30-16-00-49-986-Formal-assessment-Recent-WinSAT#scribd
I think that if you subtract 365 from that number, you'll be in previous year.
That number seems to be days since the year 0. The first part might be the number of days, taking into account leap years, etc). The second part the time coded in some way.
I have a report I am trying to modify in Crystal. It has a data field that has a formula in it, but I want to use another formula.
This is an example of what I am trying to do.
[((# Days in January) – 15) x (Market Rent/(# Days in January))]
+ [((# Days in February) – 0) x (Market Rent/(# Days in February))]
+ [14 x (Market Rent/(# Days in March))]
I have ADO commands built out for the market rent, and a start date and end date. The months in my example are just that an example. I am not sure how to take my ADO command dates that are entered in on a filter page, and put them in a formula like the one above. Any ideas?
Also, in the first and last para. the -15 and the 14 are for a date in the middle of the month. So if the start date was on the 15th of Jan, and the End date was the 15th of march. This formula would calculate my loss of rent during vacancy.
If I'm reading your question correctly, you want to take a date field and find out how to measure the number of days in that month, the month before it, and the month after it. Here's some Crystal formulas to help you out. Let's assume your date field is called {#DateFld}:
To find the number of days in a particular month relative to a particular date, try this:
local datevar X:=cdate(dateadd("m",0,{#DateFld}));
datediff(
"d",
date(year(X),month(X),1),
date(year(X),month(X)+1,1)
)
I recommend you copy & paste this in 3 different formulas:
- In the 1st formula, replace the "0" with a -1 to get the number of days in the previous month.
- In the 2nd formula, don't change anything. That'll get you the number of days in the current month (i.e. the month that {#DateFld} is in)
- In the 3rd formula, replace the "0" with a +1 to get the number of days in the next month.
For example, if {#DateFld} is March 10th, 2011, the 1st formula will give you 28, the 2nd will give you 31, and the 3rd will give you 30.
Is there a function in Haskell that will allow me to enter component of a date (like a string representation or day month year components) that I can get information from (like day of week, days in a month, etc.)?
I've looked online and it looks like there are a lot of custom libraries, but I'm hoping there's one in the standard prelude library of ghci 10.6.4 that's just not well documented?
Are Data.Time.Calendar and Data.Time.Format in the time library sufficient?
You can parse a string representation of a date and get the length of a month using gregorianMonthLength. Not sure about day of the week, though you could format the date as a string using a format that just displays the week day.
A quick Google search turns up this, which may be what you want. It lets you parse strings representing dates and extract information from them.
You can find the day of the week with mondayStartWeek or sundayStartWeek, depending on whether you think a week starts on Monday, or on Sunday. Both functions are in Data.Time.Calendar.OrdinalDate.
λ> snd $ mondayStartWeek $ fromGregorian 2017 10 3
2
In the above example, the return value is 2, which indicates the second day of the week. Since the function is called mondayStartWeek, Monday is the first day, so 2 corresponds to Tuesday. This is true of October 3, 2017.
A warning regarding week numbers
Both functions return a tuple, where the second element is the week day. As far as I can tell, that should be trustworthy.
The first element, however, is the week number of the year. Be careful with that, because the rules for week numbering are political. If I remember correctly, in USA, week 1 is the week that contains January 1. That's not the case in Denmark, where I live. Here, week 1 is the first week where Thursday falls in the new year. This can mean that December 31 can fall in week 1 of the next year. IIRC, this is the rule for many other European countries. Some years, the American and the European week numbers align, but some years, they don't.
