In Anne Frank: The Diary of a Young Girl, what hobbies and interests did Anne develop in hiding?

Of course, the diary itself is Anne's main hobby. She keeps it throughout the period in hiding, editing it frequently (especially in 1944) with the hope of publishing it after the war is over. She also writes a few stories and poems, but her diary is her main form of amusement while in hiding. She reads everything she can get her hands on, including books intended for adults. This is a frequent issue between her and her parents, especially her mother, who does not believe she should be reading books intended for grown-ups. At various points throughout the diary, Anne mentions that she is studying French and math, which she hates, with her father. Above all, though, Anne amuses herself through observing the behavior of the others in the annex and by fantasizing about life after the war, when she will be free. She also devotes much of her time to thinking about Peter. This, of course, is one of the most poignant aspects of the diary; the reader knows that her aspirations and her fantasies will be cut short when she dies in a concentration camp.

Anne has discovered a talent for writing--fiction, stories, fantasies about Peter and what their lives might be like once they return to the outside world, and perhaps most importantly, her self-reflections (diary).  She also reads quite a bit and daydreams.  All the hobbies and interests the people in hiding engaged in had to be quiet as noise would call attention to their hiding spot.

Anne Frank lived with her family and several other Jews in a hidden annex for a period of a little over two years.  During that time, Anne spent much of her time reading and writing.  She read to pass the time, and wrote in her diary almost daily.  She expressed that she someday wanted to become a journalist.  Anne also enjoyed spending time with Peter van Pels, who she developed a crush on.  Peter was also a Jew who lived in the annex with his parents.  Her first kiss was from Peter.  

Collecting things became a hobby of Anne's.  She kept a collection of postcards and magazine clippings with movie star photographs.  She described in her diary how she "put up some more film stars in [her] room but this time with photo corners."  She used the photo corners so that she could easily switch out photos for variety, rather than pasting the pictures directly onto the wall.  Even though Anne could no longer visit the theater to see these actors and actresses, she enjoyed seeing their photographs each day on her wall.  The royal families of both Holland and England were another interest of Anne's.  She kept postcards with photos of the two English princesses, Elizabeth and Margaret.  She also had postcards with photos of the exiled Dutch royal family.  Anne even recorded the birthdays of the royals and drew up their family trees.

How did Anne Frank keep busy while in hiding?

Anne throws herself into her writing and studies while in hiding. She mentions writing poems and short stories, sometimes as gifts for the other people in hiding with her. And obviously, she writes and edits her diary in her spare time. She also studies short-hand, English, French, history, algebra, religious topics, and other academic topics.

Reading is also a major past-time. From movie magazines to history books, Anne devours whatever she can get her hands on. Anne is a bit frustrated that her parents are very strict about what she is allowed to read, since they are nervous about her perusing material dealing with "adult" topics.

Later on, Anne forms a friendship with Peter van Daan and the two spend large amounts of time talking alone together, though the adults become concerned that their doing so is improper.

How did Anne Frank keep busy while in hiding?

When Anne and her family move into hiding, life becomes quite boring for her because she does not have much to do. As a result, she turns to reading and writing as a way of keeping herself busy. In several instances within her diary, Anne indicates that she is keeping herself busy by reading different books that range from novels to poetry. In one such instance, Anne claims to have read The Zaniest Summer at least four times, just to keep away the boredom. To articulate her new habit of reading during her days in hiding, Anne says that every other week Mr. Kleiman brings her a couple of books written for girls her age. Additionally, it is evident that Anne keeps herself busy writing her diary, which she updates from time to time. In addition to her diary, Anne stipulates that she spends time translating chapters from La Belle Nivernaise and other French books.
