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.
For example, the year of 2000 had 54 weeks. Its first week consisted of only one day which was Saturday, the 1st of January. And the last week of 2000 included just one day too. It was Sunday, the 31st of December. Conclusion From the point of view of mathematics, there are 52 1/7 (or 2/7) weeks in a year. It means 52 full weeks. But on the calendar there will be 53 or 54 separate weeks though one or two of them will be incomplete. So the answer to the question about the number of weeks in a year depends on what you prefer to call a week. If you mean seven days from Sunday till Saturday, then no year will have more than 52 weeks. But if a week for you is a separate line or column in the calendar, then there may be up to 54 weeks in a year.
