Berts bravader

Berts bravader (Swedish: Bert's exploits) is a diary novel written by Anders Jacobsson and Sören Olsson and originally published in 1991. It tells the story of Bert Ljung from 2 January to 1 January during the years he turns 14 and 15, covering the spring term in the 7th grade, the upcoming summer break, and the autumn term in the 8th grade.

No specific calendar year almanac is used. As standard, Bert opens the chapters with the words "Tjena!" and finishes with "Tjena, tjena – mittbena". Bert writes diary for each week during this calendar year, not each day like the previous, but in turn the chapters are longer than in the Bert's betraktelser trilogy. It also aired over the Unga Efter tre radio programme back in the early 1990s.
