Year of columbine shooting

How it works

Columbine shooting year and Columbine year, in this search, mean the civil year of that Tuesday: 1999. They do not mean a festival, a public holiday, or a school in-service day. This page sits in a holiday folder because of a crawl, not because 20 April is a feast. It is an anniversary date on a calendar. Treat it as a date. Do not treat it as a celebration.

The year is a four-digit Gregorian number. The day inside the year is 20 April. If a quiz asks only for the year, 1999 is the answer. If a memorial asks for the anniversary, you also need the month and the day. A year alone cannot mark a wall calendar. A date without a year cannot tell you which decade you mean. People who say “the Columbine year” as shorthand are naming 1999, not the 1998–99 academic span that crossed two Januaries.

1999 was not a leap year. April had thirty days, as it always does. The weekday that year was Tuesday. Later anniversaries keep 20 April and drop the original weekday. 20 April 2026 was a Monday. 20 April 2027 is a Tuesday again, because weekdays cycle. A reminder that repeats “the third Tuesday of April” will miss the date in most years. Repeat 20 April, not the Tuesday.

Year: 1999. Date: 20 April 1999, Tuesday. Place: Columbine High School, Jefferson County, Colorado. Anniversary: 20 April each later year, weekday variable. Not a U.S. federal holiday, not a school feast, not a civic carnival.

The 1998–99 school year began in 1998 and ended in 1999. News, courts, and memorials stamp the event with the civil date in 1999. If you are filing, citing, or setting a silent reminder, use 20 April 1999. If you are counting completed years from that Tuesday, count from 20 April to 20 April. In September 2026 the April anniversary for this year has already passed. Subtraction of the years 2026 minus 1999 is a year-label count, not a to-the-day age, until you name the April date.

A year is a label on a grave date. It is not a feast, and filing it with holidays does not make it one.

How to keep the year without turning the day into content

If you needed the Columbine year for a caption, a paper, or a search, 1999 is the whole of it. If you are setting a reminder, use a private recurring date on 20 April and leave the original year in the note so the software does not pretend the event is new. If you are writing for other people, do not stage a reenactment, a countdown, or a “holiday hours” box. Schools and towns that mark the anniversary do so locally. Their notice is the notice. This page will not invent a programme.

April 20 is also other things in other lives: birthdays, tax leftovers, ordinary Tuesdays. Those other uses do not cancel the memorial, and the memorial does not cancel them. What it does not become is a shopping occasion. There is no Columbine Day on a federal list. There is no substitute Monday. There is a date in 1999 and a returning 20 April.

If you came here from a true-crime binge, the calendar fact you asked for is still only the year and the day. The rest is other people’s loss. Stop when you have the stamp. 1999. 20 April. Tuesday. Jefferson County, Colorado. That is the record this holiday-shaped URL can honestly hold.
