Just for the benefit of the readers, I'm gonna make this first chapter just a quick little reference guide for the timeline in my headcanon. I've used it constantly while writing these drabbles. I mostly use it as a frame of reference for how old the characters are in relation to what year/month the drabble takes place in.

For reference, I think the original Peanuts canon (whether you're counting the strips or the animated specials) takes place from when the characters are 4 or 5 until they're about 9 or 10. So 1952 thru about 1958, give or take.

First, birthdays:


Schroeder's birthday - January 18th, 1947

Lucy's birthday - April 10th, 1947


And now school years and the ages they are AFTER THEIR BIRTHDAYS each year:


1952 - 5 yrs - Kindergarten thru 1953

1953 - 6yrs - 1st grade thru 1954

1954 - 7yrs - 2nd grade thru 1955

1955 - 8yrs - 3rd grade thru 1956

1956 - 9yrs - 4th grade thru 1957

1957 - 10yrs - 5th grade thru 1958

1958 - 11yrs - 6th grade thru 1959

1959 - 12yrs - 7th grade thru 1960

1960 - 13yrs - 8th grade thru 1961

1961 - 14yrs - 9th grade thru 1962

1962 - 15yrs - 10th grade thru 1963

1963 - 16yrs - 11th grade thru 1964

1964 -17yrs - 12th grade thru 1965

1965 - 18yrs - college freshmen thru 1966

1966 - 19yrs - college sophomores thru 1967

1967 - 20yrs - college juniors thru 1968

1968 - 21yrs - college seniors thru 1969

1969 - 22yrs - master's degree 1st year thru 1970

1970 - 23yrs - master's degree 2nd year thru 1971


After that, I don't have a chart, but I hope this is helpful!
