It depends on the subject matter, topic, and purpose of writing your article. The length of your article and the references you review during writing your article also determine the time you devote to finish your article.
Abstract is the last section to be written it takes me a total of 3 hrs. Introduction takes me a total of 2 weeks, materials and methods 2 days, discussion 2 weeks. However, i never write one article at a time, I usually have 3 papers running together
It depends that how much you are prepared for writing. If you have all the data and references ready then it may take around four weeks. It also depends on the length of paper you are writing.
Paper writing is an art and some people are very good at it. However, it all depends on the subject matter and the available data. Normally it take more than a month to get the zero draft and then you read it again and again to rectify the mistakes and add new references.
It helps a lot if you keep on reading the papers written by the expert in the filed. It helps to organize your text presentation well and also on what section you must emphasize.
In all I will say about two months to finalize a paper.
The young researcher writing their first paper are facing same problem every where. But senior scientists should show them the correct process of paper writing. First paper will take more time in writing. Finally time will be optimized after some experience.
It depends on... so much. If there is to present archive material ore other materials than more time is necessary, but some weeks I have to calculate, often interpretations change because quite new materials show another picture as before. To correct the text and discuss the results with other colleagues before sending to a magazine endures also some time.
A tricky question. For me, it depends on many different things. If I have all data collected it can take at least 2 weeks, as after writing an article I usually put it aside.
Writing is the easy part. Identifying interesting topics to write about worth publishing is time intensive. Searching and critiquing previously written work is also time extensive. Short articles may take a few days to weeks. Long articles may take many months, or even years. Setting the article aside for a week or two is also helpful for second, third, and final drafts- giving time to rethink what is missing or extraneous.
It took me a good year to get permission to publish material from an archive. The process of examining legal requirements, for example for persons directly or indirectly connected with the dictatorships of the 20th century, took so long. So now I start again to work on texts concerning this project. In the meantime, some completely different topics are discussed, so that you first have to familiarize yourself with the material again. Therefore, there is no very uniform measure of the answer to the question asked.
