Is Sirius still Harry's godfather in the new timeline? Also, according to Ms. Rowling's timeline, Bill Weasley was born in 1970, which means he started at Hogwarts during the 1981-1982 school year, ten years before the Trio. The Marauders, Lily and Snape started at Hogwarts during the 1971-1972 school year, so their Hogwarts years didn't overlap.

Where's Peter, we haven't actually seen him since Harry and Ginny traveled back in time.

Ginny's full first name is Ginevra.

You didn't give the title for the story that gave you the idea for Sirius' return.

How did Dumbledore know that Greta's favorite food is frogs?

Ron's birthday is March 1st. Also, Ginny's birthday is August 11th, so the necklace would be an early birthday gift.

Ginny's true first name is GINEVRA NOT VIRGINIA. Please correct this mistake.

This was great.

One slight problem with this chapter: When Harry gave Ginny the unicorn in a previous chapter, you said the eyes were emeralds. In this chapter they're sapphires? Two very different stones as one is green and the other is blue.

on the last chapter when ginny said she got eleven owls, but was it outstanding, exceeds expectations, poor or troll?" and yes, and unfortunately you have to include the words, kind of like this I've got eleven outstanding on all 11 of my OWLs or I've got 6 Outstandings and 5 Exceeds expectations on my OWLs. Yes you've got to include these things just so you know you've forgot to include them so knowing the story I'm going to say Ginny had Probably 5 6 exceeds Expectations and 5 Outstanding score on her 11 OWL exams.

I remember there is another probably with your time-frame in your story, one that William Bill Weasley was in his second year, when Sirius Black, James Potter and Remus Lupin were in their 6th year, however this is not the case because the time frame of those 3 people are these

1971-1972-1st
1972-1973-2nd
1973-1974-3rd
1974-1975-4th
1975-1976-5th
1976-1977-6th
1977-1978-7th

and Bill Weasley was born in 1970 and Charlie was born in 1972.

So Bill and Charlie's time frame would be this
Bill years at Hogwarts
1981-82-1st
82-83-2nd
83-84-3rd
84-85-4th
85-86-5th
86-87-6th
87-88-7th

Charlie's years at Hogwarts
1983-1984-1st
84-85-2nd
85-86-3rd
86-87-4th
87-88-5th
88-89-6th
89-90-7th

and That's all you need to know. When writing a story use the Harry potter wikia or I'll just give you the years of them.

And Arthur Weasley and Molly Weasley went to Hogwarts together, but they never went to school with Potter, Lupin or Black unless it was an older sibling of course, based on Sirius Black ancestry I wouldn't be surprised if Molly and Arthur went to school with Bellatrix or some other black family member considering Arthur and Molly were born around 1949/1950 so Molly and Arthur's Hogwarts years are these:
1961-1962-1st
1962-1963-2nd
1963-1964-3rd
1964-1965-4th
1965-1966-5th
1966-1967-6th
1967-1968-7th

Bellatrix was in school at the same time as Arthur and Molly Weasley
considering Bellatrix was born in 1951111962. so Bellatrix's school years would be this:
1962-1963-1st
1963-1964-2nd
1964-1965-3rd
1965-1966-4th
1966-1967-5th
1967-1968-6th
1968-1969-7th

and same goes with Andromedia Tonks(Nymphadora's mother) and Narcissa Malfoy(Draco's mother).
If you want more information I suggest, you go to harry potter wikia "dot" com

Kind of Messed up the time frame on this one, because the years of harry's hogwarts years goes like this

91-92-1st
92-93-2nd
93-94-3th
94-95-4th
95-96-5th
96-97-6th
97-98-7th

And This began in the 6th year which the beginning of which is in 1996 and Sept, 1, 1996 is on a Sunday not a Saturday now please people when writing storys try to look at the time frame on the story and the calendars on your computers before you write anything else if you don't mind.

I like the result of the time travel and the best thing is... no Draco lol

Dudley is also a wizard...wow

Finally, Harry and Ginny are together
