People are confused as to how to sit shiva and how to properly pay a shiva call. Because people do not know, and because talking about death makes people nervous and awkward, the shiva house often turns into a festive gathering filled with nervous chatter, instead of the proper house of mourning.
The average number of days in a month is around 30.4. With 24 hours in a day, this is an average of about 730 hours per month.
The number of weeks in an average Gregorian year equals to approximately 52.18 weeks (365.25 days divided by 7), and the number of weeks in an average month is close to 4.35. Hence, when performing weeks to months calculations it is not sufficient to simply assume that a month equals to four weeks, i.e. 4 x 7 = 28.
