Being a native dutch speaker who is also fairly good in English, I was asked to translate an existing software package. Most things were easy to translate (with the help of a good Dutch-English financial dictionary). So far, so good. However, I'm limited to a fixed length for most field names. So I ran into a problem when I needed to translate the following field name:

- Datum t/m

Which is essentially the same as:

- Date up to and including

My question is: is there a way to abbreviate "up to and including" or is there a synonym which means the same? We've tried the words "to" and "until" but in both cases this means that you are referring to the day before the date entered. This really is a problem to us because the software package is designed for the exact depreciation of fixed assets. Since the package also depreciates to the exact day, stating the correct date is absolutely essential. As you will understand, it certainly makes a difference when the depreciation stops at 12-31-2005 as opposed to 12-30-2005.

Many thanks for your help!

How about 'end date', or perhaps 'last day' or 'final day'?

There is not really another prepositional phrase with the precision of "up to and including" as it leaves no doubt that the date following the phrase is included. It is regularly used in legal documents.

I don't know if this will help http://www.google.com/search?hl=en&lr=&q=end+of+day
They even abbreviate it EOD
Good suggestions, I will try those, thanks!!!

'Up to and including' is obviously too long. what I use is u/i. I work as an English teacher in the bilingual stream of a comprehensive school and have come across several words in Dutch that are difficult to translate. Another example: for 'uitroosteren' I use deschedule.

According to the Merriam-Webster dictionary, "through " could do:

4. —used as a function word to indicate a period of time: such asa : during the entire period of
  • all through her life
b : from the beginning to the end of
  • the tower stood through the earthquake
c : to and including
  • Monday through Friday
