He was baptised one day later at the local church as evidenced by an extract from the register of baptisms for Mihalj Šilobod, located at the parish in Podgrađe Podokićko.

He pioneered literacy efforts for the low-income Croatian community in a number of parishes, making him a standout even in that very deprived region.

Nedjelja, he particularly advocated for the construction of the first public school in Sveti Martin pod Okićem in 1761, the neighboring parish of where he was born.

In fact, his father Andrija claimed that the priest signed all of his documents with the simple name "M. Šilobod" out of a desire for humility and to avoid the privileges and trappings of nobility.

In Arithmetika Horvatzka, he uses both his birth and baptismal surname, Šilobod, and his second ("different") last name, Bolšić, to honour the feminine lineage of his family tree, which originated with his grandmother and had a profound impact on his life's social orientation.

Many people from Hrvatsko Zagorje and Sisak Posavina, as well as Catholic Church leaders and a high-ranking military delegation from the Slunj Regiment, were documented as having travelled to Sv.

[9] After moving into the rural countryside and immersing himself in the local culture he began compiling traditional songs and hymns that had been passed down orally until then.

Mihalj identified that there was a severe lack of accounting skills in local organisers who struggled to handle even the most basic financial and business calculations.

[1] The book's content, explanations and exercises serve their intended function by including the computation of mixes and other calculations that are part of everyday economic mathematics.

Because of this, Šilobod realised he was up against an enormous challenge: his handbook would be the first documented record of the preexisting mathematical language in the Kaikavian region.

[9][11] As of today, this work is still studied in the Accademia Nazionale di Santa Cecilia in Rome and is considered a great theoretical guide to choral singing even after a century has passed.

[1] Because it was the first appearance of the systematically used Croatian mathematical vocabulary, Šilobod's Arithmatika Horvatzka has had enormous cultural value in Croatia.

In addition, the manual played a crucial part in the education in Croatian people at a time when there was a pressing need to increase students' understanding of accounting's function in business and economics.

[7] Irena Mišurac Zorica concluded in her analysis of the work that Mihalj Šilobod Bolšić demonstrated a very high pedagogical and methodical maturity, creating a standard for further development of mathematics curriculum and education.

[12] In addition to the stamp, a scientific symposium was organised in Sveta Nedjelja to honour Mihalj Šilobod Bolšić.

The Samobor Museum produced a book in 2009 that included the writings of the seven people who had taken part in the scientific meeting: Ph.D. Stjepan Razum, prof. Domagoj Sremi, prof. PhD Alojz Jembriha, MSc sc.

These writings help provide light on the life and accomplishments of Mihalj, an important figure in the spread of mathematics education in the 18th century.

To celebrate the event, the Museum issued a reproduction of the entire Arithmatika Horvatzka in separate volumes, and the collection includes a transcription of Šilobod's prologue to the work in its appendix.
