In a given period (Yearly/Half- yearly/ Quarterly/Monthly), the journal impact factor of a journal is the average number of citations received per paper published in that journal during the one or two (one or more) preceding periods.
For example (Calculation of Journal Impact Factor(JIF) Yearly) , if a journal has an impact factor of 5 in 2009, then its papers published in 2007 and 2008 received 5 citations each on average. The 2009 impact factor of a journal would be calculated as follows:
A = the number of times articles published in 2007 and 2008 were cited by journals, books, patent document, thesis, project reports, news papers, conference/ seminar proceedings, documents published in internet, notes and any other approved documents during 2009
B = the total number of "citable items" published by that journal in 2007 and 2008. ("Citable items" are usually articles, reviews, proceedings, notes or any other documents pre-reviewed before publishing it)
2009 impact factor = A/B.
(Note that 2009 impact factors are actually published in 2010; they cannot be calculated until all of the 2009 publications have been processed by the indexing agency
