The incubation period following exposure to the hepatitis E virus ranges from 2 to 10 weeks, with an average of 5â6 weeks. The infected persons are believed to excrete the virus beginning a few days before to around 3-4 weeks after the onset of disease.
For people paid every two weeks, there are 26 pay periods in a year. Two weeks makes 10 business days, for a total of 260 working days, not accounting for vacation time that you take. In the US people commonly say there are 260 weekdays/work days in a year or 2080 work hours in a year based on 52 weeks per year. (260 = 5wkdys/wk*52wks) (2080=40hrs/wk*52wks/yr) The number can vary by year. For example, 2012 had 261 weekdays and 366 total days.
In 1981, the General Accounting Office performed a study on American work days. It evaluated the number of working days each year over a 28-year period, which is the length of time it takes for a calendar to repeat itself. Most years (17 out of 28) had 261 working days. Seven years had 260 work days, and four had 262 work days. The study also found that there are approximately 2,087 standard working hours in a year.
