A Bar Mitzvah is a ceremony which takes place on the 13th year of a Jewish male’s life (to the day).
How could it exist that [of two Jewish boys] Jim would be born on the first day of the month and John on the last (of that same month and year), yet 13 years later John reaches the age of Bar Mitzvah before Jim?

But taking an important extract out of it :
Here too, since Adar has only 29 days, he becomes a bar mitzvah on the 1st day of Nissan.
However, the Binyan Zion (158) rules that he becomes a bar mitzvah on the first day of Rosh Chodesh Adar, which is the 30th day of Shevat, since he was born on the first day of Rosh Chodesh Adar. This novel view, which makes him a bar mitzvah over a month earlier, is based on an unproven thesis that the status of Rosh Chodesh can determine a birth day.

John was born on the last day of, say, February, while Jim was born on (for example) March 1. The exact months aren't specified, so John could be born on the last day of a previous month.
Alternatively (with the edit):
Jim isn't Jewish.
Also possible (with the edit):
Jim is a girl, and celebrates her bat mitzvah, not bar mitzvah.
Note: There was another edit, now ALL my solutions are invalid. At the time of posting they were valid, though.
Now possible with new edit:
Jim dies before he turns 13.

The Hebrew calendar not only has two months that are sometimes a day longer than otherwise (to avoid Yom Kippur falling on Friday or Sunday, or Hoshana Rabbah on Saturday); it also inserts an entire leap month (Adar I, preceding Adar II, which in common years is simply called "Adar") in 7 of every 19 years. And these peculiarities are related to the odd interpretation of the Bar Mitzvah age.
