Throughout JoJo's Bizarre Adventure, there are a few cases where the timeline does not match up with previously stated dates or dates end up being changed in future chapters, creating inconsistencies.

Date of Stardust Crusaders
One of the largest contradictions in the series is the date that Stardust Crusaders took place. Stardust Crusaders is a journey taking fifty days, beginning either in 1987 and ending in 1988, or beginning in 1988 and ending in 1989.

1987-1988
1987 is used in JoJo6251, the anime, and a few times in the Part 4 manga. It is never explicitly stated in the Part 3 manga.
 * The anime attempts to keep the date consistent with the year being 1987, but they keep Jotaro's age being 28 in Part 4. As the beginning of Part 4 takes place in April 1999, this does not match with Jotaro's birth date being 1970 from JoJo6251 and his Aquarius zodiac sign from his manga biography . Nonetheless, his birth year and zodiac were never stated in the anime.
 * Josuke is said to be born in 1983 and was four years old when he gets his fever.
 * In the anime, Keicho states that his dad starts mutating when DIO was defeated eleven years ago in 1988, when Okuyasu was four years old.

1988-1989
1988 is used in Part 4 and Part 6, with several things in Part 6 being based on Part 3 taking place in 1988.
 * Jotaro says DIO got his stand in 1988 in Part 4. He and Keicho also say the battle against DIO occurred "10 years ago", meaning it ended in 1989 since Part 4 takes place in 1999.
 * DIO says he met Pucci in 1988.
 * Pucci was born in 1972 and he was 16 when meeting DIO (https://s2.mangadex.org/data/1fd92df8b36837e91f3379216212c8de/x2.png)
 * Jotaro is 28 in Part 4 (1999-28=1971, 1971+17=1988) and 40 in Stone Ocean (2011-40=1971). However, his birth date is said to be 1970 in JoJo6251 which doesn't add up.

Koichi's Age
Koichi is said to be 18 in 2001 (Chapter 454) when he is supposed to be 17 as his birthday is in March, 1984.

Narancia's Age
Originally born in 1984 with a Leo zodiac sign in Chapter 472. This date and zodiac is kept in the anime, despite his birthday later being changed to May 20, 1983 with a Taurus zodiac sign in Chapter 572.

Trish's Age
In Chapter 540, her birth date is April 14, 1986 but in Chapter 591, it is changed to June 8, 1985.

Steel Ball Run Dates
Stage 8 starts on December 28, 1890 and is said to last 2 days, whereas the final stage afterwards lasts approximately 30 minutes. However, the date is somehow January 19, 1891 by the time the race finishes.

JoJolion Ages
Tsurugi was originally 2 years old in the Ultra Jump release of JJL Chapter 7, but was corrected to 9 years old in the volume release. He later becomes 10 years old throughout the story.

Joshu is originally 18 years old and then says he's 19 in JJL Chapter 57. While Tsurugi's age has changed from nine to ten years old in the character biographies in each volume, Joshu's age remains as 18.
