This is a timeline for the Silent Hill series based on as much official information as possible. Please ensure that all dates are official, referenced and appear chronologically. Please also note that while this timeline is primarily factual, some dates may be speculated or inferred.
The dates for Silent Hill: Origins, Silent Hill, Silent Hill 2 and Silent Hill 3 are technically unknown. Some dates for these games can be obtained in a promotional diary supposedly written by Alex Shepherd, but it is unknown how canon they are and they are initially crossed out. The dates in the diary place Origins in 1976, Silent Hill in 1983, Silent Hill 2 in 1993 and Silent Hill 3 in 2000, but again, these shouldn't be taken as absolute canon fact.
The ages of SH1/SH2/SH3 characters are provided in the Book of Lost Memories. The ages for Silent Hill: Homecoming characters are provided in the manual. Everything else is taken from the games.

- In October, the events of Silent Hill: Homecoming occur.
- The events of Silent Hill: Shattered Memories occur in the Shattered Memories canon.
- A shop in Central Silent Hill in Silent Hill says "Since 1987" on it, implying the game is not set before 1987, but the texture is blurry and if the date was meant to be canon is ambiguous.
- Alessa's History states that Harry's wife died 11 years before Silent Hill. However, this makes no sense as Cheryl, who is 7 years old in Silent Hill, wouldn't have existed then and Harry's wife is seen adopting Cheryl in the opening. As well, Harry states his wife died 4 years ago in Silent Hill. This was likely a goof.
- Although the date for Silent Hill 3 is unknown, a photo of a lake called "Landscape Photograph Exhibition", found near Monica's Dance Studio, seems to have "2000" on it, implying it is set in the early 21st century, but it's so blurry that it's difficult to know for sure.
- There have been some multiple contradictory dates for Silent Hill: Downpour (Anne's Story is set during Downpour). Bobby Ricks's calendar lists no month or years, but states the first begins on a Saturday.  A calendar in a garage near the beginning of the game shows August in which the 1st begins on a Tuesday, which could mean 2006 or 2017. The missing poster of Ariadne Johnson says she is 8 years old and was born in 1996, meaning the game cannot occur before 2004. However, this does not necessarily mean Downpour is set in 2004 as it's possible that the poster either means she was 8 when she was abducted, or that the missing poster is outdated.
- In the first Silent Hill, Harry Mason carries what appears to be a Smith & Wesson Sigma series handgun. The Sigma series debuted in 1994, suggesting that the game takes place no earlier than that year. However, when Silent Hill was released in 1999, Konami had no way of knowing how successful it would be, or that it would spawn an entire franchise; it is possible the first game was originally set in or around 1999, but was later retconned to the 80's to account for Heather Mason's age in Silent Hill 3. (The other alternative would have been to set Silent Hill 3 in what was, at the time of its 2003 release, the far off year of 2016.)

- ↑ The town celebrated its 150th anniversary in 2003.
- ↑ The Book of Lost Memories - Alessa's History
- ↑ Medical Report
- ↑ Another Crimson Tome reveals Cynthia is 29 years old during Silent Hill 4.
- ↑ Maria states the calendar in Amy's room is "10 years old", placing her death in 1984.
- ↑ Her missing poster, which Elle posts in 2007, states she is 15 years old.
- ↑ The Little Baroness went missing in 1918, and The Arcade takes place "75 years later." In addition, the spiral staircase area is labeled "19181993", making the year clearer.
- ↑ Newspaper Article
- ↑ Eileen tells Henry that Joseph disappeared 6 months before he moved in. In the introduction of the game, it's said that Henry has been living in Room 302 for at least 2 years. 2001 - 2 = 1999.
- ↑ There are two things that support this. Apparently, the timeline that came with the Silent Hill 4 guide says that SH4 is set 18 years after SH1. The second is the placement of days of Walter's Diary.
- ↑ After the summer, our town had this big anniversary party... And then, that whole week, Alex didn't come by and he didn't call me. It was weird, so I went over to his house. No one answered the door. I could hear Alex's mom crying... His dad came out and told me that Alex had left. That was a few years ago and I still haven't forgiven Alex for just leaving like that without even calling me. —Elle Holloway's Diary
- ↑ Adam's age and his birth date mean Homecoming must take place between April 2007 and April 2008. In October, Alex states in his diary that he plans on escaping from the hospital and hitching a ride to Shepherd's Glen, meaning that it would be impossible for Homecoming to take place in 2008 or else Adam would have been 54 years old.
- ↑ Cheryl Heather Mason was born in 1983. She was seven years old in 1990 when Harry died in a car crash. Dr. K states Cheryl has been denying her father's death for eighteen years. 1983 + 7 + 18 = 2008. As well, there can be boxes found in Orion Hunting Lodge with "2008" written on them. In the Dixon Bridge Control Tower, an almanac can be found with "2008" on it.
- ↑ There is a note in the game that says "Sat 2/20/10". In addition, the calendar in the protagonist's room corresponds to a June 2010 calendar.
