Any online week-of-the-year calculator eliminates the need for calculations, but the steps to determine the week of the year are simple.

Look at a calendar, beginning at January of the year in question and find the first Sunday of that year, then count each successive Sunday until the week under consideration.

Another way to determine the week of the year is to determine the day of the year, calculating how many days it has been since the first day of the year. Some calendars provide this information.
