WASHINGTON — The nation’s Tuesdays filed a formal complaint Tuesday with the Bureau of Calendar Affairs, alleging a “sustained and casual pattern of misidentification” in which the second day of the work week is routinely described as “basically Monday.”

The 14-page grievance, submitted on behalf of all 52 Tuesdays in the calendar year, demands a public apology, a distinct identity, and an end to phrases such as “Monday, part two,” “the Monday that stayed too long,” and “ugh, still Tuesday?”

“We are not a continuation,” read a statement delivered by the Tuesdays at 9:15 a.m., after what sources described as a “brief and unremarkable” wait. “We are a day. We have our own date, our own weather, and, in many cases, our own recycling pickup.”

The filing notes that Tuesdays have endured the indignity quietly for centuries while Friday receives parades, Saturday receives brunch, and Wednesday has been granted a camel.

“Tuesday is the only day of the week that has to be described by what it isn’t,” said Dr. Lorraine Pickett-Vance, senior fellow in Weekday Perception at the Institute for the Comparative Study of Mid-Week Resentment in Dayton, Ohio. “It’s not the start, not the middle, and not the end. It is the beige carpet of time.”

Pickett-Vance added that her own research found 78 percent of respondents could not recall a single thing they did on the previous Tuesday, and that the remaining 22 percent were “probably thinking of a Thursday.”

In a rare moment of candor, the Tuesdays acknowledged in the complaint that they have never once been in the running for anyone’s favorite day. The document describes this as “not the point,” before conceding that it is “a little bit the point.”

“We’re not asking to be loved. We’re asking to be Tuesday.”

Representatives for Monday, reached for comment, said they were “exhausted” and “had no idea this was happening,” and that they themselves have long been the subject of a pending grievance involving the words “case of the.” Monday asked that the Tuesdays direct any further correspondence to its own legal department, which is staffed exclusively on Mondays and is therefore “already behind.”

The Bureau of Calendar Affairs confirmed receipt of the complaint but said it could not act until at least Wednesday, a day it described as “where things really get going,” a remark the Tuesdays characterized as “exactly the problem.”

Procedural experts say the case faces long odds. Under current rules, the days of the week may be redefined only by a unanimous vote of the other six, and Sunday has reportedly been “unreachable, in a mood.” Thursday has pledged to abstain, noting that it is “basically Friday” and therefore “above all this.”

Pending a ruling, the Tuesdays have requested minor interim relief, including a modest rebrand, a signature snack, and a single commercial in which someone says “Tuesday!” with genuine enthusiasm.

At press time, the Tuesdays had been informed that the review process would take roughly one week, which they confirmed would also be a Tuesday.
