Dorothy Miller has collected so much history for the calendar commemorating Pittsburgh's 250th anniversary that she is considering publishing a book.

For now, however, the Pittsburgh Pleasures calendar that Ms. Miller publishes every year will have to do.

This year the calendar, which she sells both individually and to businesses and government agencies that pay to have their own imprint on the back cover, has historical dates alongside the events that are a mainstay of the calendar. It also has a special 250th anniversary section on everything from "Pittsburgh Facts, Firsts and Folks" to famous Pittsburghers.

The Pittsburgh 250th calendar is the 26th Pittsburgh Pleasures calendar Ms. Miller has produced with her small company, New Pittsburgh Publications. Though she used to have an office Downtown when she ran the company with a partner, her partner died and now it is run out of her apartment in Oakland.

Ms. Miller said she had looked around the country for any other city that has a calendar like hers and has found none. She collects information from 400 groups about their events. The calendar marks the Carousel reopening in Schenley Park (April 6); The Pride Fest for gay, lesbian bisexual and transsexual Pittsburghers (June 21); the Vintage Grand Prix (starts July 19); and the Empty Bowls dinner to benefit the Pittsburgh Community Food Bank (March 9).

The photos in the calendar may look familiar to those who have used it before. Ms. Miller said she used only four new photos -- the other eight represent the best and most quintessentially Pittsburgh shots used in past calendars. There also are smaller photos sprinkled among the days of the month that Ms. Miller culled from the archives of Carnegie Library of Pittsburgh that show Downtown's Old Diamond Market arch in 1930, Oakland's Luna Park in 1905 and many other flashbacks to the city's past.

Next year marks the anniversary of the battle in which the French were defeated and Fort Duquesne was renamed Fort Pitt, creating a British stronghold in an area that had previously been controlled by the French.

The surrounding area was originally called "Pittsbuourgh" by Gen. John Forbes.

In this year's calendar, the events leading up to taking the area for the British are detailed. According to the calendar, on March 4, 1753, George Washington noted that the Point was a good spot for a fort. That fort was built on March 5, 1754, by a trader and named Fort Prince George (just think, we could be "Prince Georgians" living in the home of the Prince George Steelers).

The French took that fort the next month on April 17, and spent 13 months building Fort Duquesne. Nov. 24 marks the day in 1758 that General Forbes successfully defeated the French at Fort Duquesne. The British flag flew over the fort for the first time on Nov. 25. That's the reason the celebrations are planned throughout the coming year.

Both historical events and Pittsburgh 250 celebrations are marked in yellow throughout the calendar.
