MEMORANDUM OPINION AND ORDER

In connection with this bankruptcy appeal by Darlene Unruh (“Unruh”), appel-lees Kmart Corporation and certain of its domestic subsidiaries and affiliates (collectively “Kmart”) have tendered their motion to dismiss Unruh’s appeal as untimely. That motion was presented on June 14, 2004, and this Court gave Unruh fully four weeks — until July 12 — -to file her response.

*845That filing date had apparently come and gone with no input from Unruh, for the District Court Clerk’s Office file and docket reflected no response as having been received from her. But it then occurred to this Court that counsel such as Unruh’s, who had already managed to blow an unambiguous jurisdictional deadline, might well have tendered her court-ordered response to a court other than this one that had entered the order. Sure enough, when at this Court’s request its docket clerk checked the enormous Kmart bankruptcy docket, she located Unruh’s Response to Motion To Dismiss Appeal as having been filed there — a document- that carried the wrong caption (“In the United States Bankruptcy Court,” not the “United States District Court”), the wrong case number (02-2474, which is the Kmart Chapter 11 case number in the Bankruptcy Court, not the correct District Court number as shown in the caption of this memorandum order) and the wrong judge’s name (Honorable Susan Sonderby, not this Court).1

But there is no need to dwell on such manifestations of careless practice. Instead this Court has focused on the substance of the motion to dismiss and has found it to be unanswerable for the reasons discussed hereafter.

Bankruptcy Rule (“Rule”) 8002 sets a 10-day time limit for filing a notice of appeal from a bankruptcy court decision, and the failure to comply with that timing requirement is a jurisdictional flaw that mandates dismissal by the district court (see, e.g., In re Maurice, 69 F.3d 830, 832 (7th Cir. 1995); Stelpflug v. Fed. Land Bank of St. Paul, 790 F.2d 47, 49 (7th Cir. 1986)(per curiam) and cases cited there). That 10-day clock begins to tick upon entry on the bankruptcy court docket of the order sought to be appealed (see Rule 8002(a) and Stelpflug, 790 F.2d at 50). In this instance that docket date was February 13, 2004. And unlike Fed.R.Civ.P. 6(a), which would add any intervening weekends and holidays to that 10-day period if the matter were subject to the Federal Rules of Civil Procedure, Rule 9006(a) provides for such addition only if the prescribed period is shorter than eight days (Maurice, 69 F.3d at 832-33).2 All of that being the case, Unruh’s notice of appeal had to be filed not later than February 23, 2004 — but it was not in fact filed until February 26.

By way of seeking to excuse his thus having missed the plainly-spelled-out 10-day deadline for filing the notice of appeal here, Unruh’s counsel points to his asserted lack of knowledge of the entry of the order appealed from (something that is really inexcusable, given Judge Sonderby’s February 11 oral ruling coupled with her contemporaneous statement that the written order would then issue) and to a miscalculation that he says was created by adding three days for mailing. Why? Because, he says, that is the operative rule in the Nevada state courts.3 And Unruh’s *846counsel then seeks to use those excuses as a springboard for invoking the Supreme Court’s expansion in Pioneer Inv. Servs. Co. v. Brunswick Assocs., Ltd. Partnership, 507 U.S. 380, 113 S.Ct. 1489, 123 L.Ed.2d 74 (1993) of the concept of “excusable neglect” contained in Rule 9006(b)(1).

But once again Unruh’s counsel has really not looked at the operative rules. Here is the relevant roadmap:

1. Rule 8002 prescribes the time for filing notices of appeal. As already discussed, it is Rule 8002(a) that mandates such filing “within 10 days of the date of the entry of the judgment, order, or decree appealed from.”

2. Rule 9006(b)(1), which was at issue in Pioneer Inv., states the general “excusable neglect” principle that was construed there. But that provision for possible enlargement of allowable time does not apply here, for it begins with “[ejxcept as provided in paragraphs (2) and (3) of this subdivision.”

3. In turn, Rule 9006(b)(3)(emphasis added) provides an express limit on any enlargement of time in the situation now before this Court:

The court may enlarge the time for taking action under Rule[ ]... 8002 [among others] only to the extent and under the conditions stated in those Rules.

4. To return then to Rule 8002, its subdivision (c)(2) (emphasis again added) contains a strict limit on the granting of relief for “excusable neglect”:

A request to extend the time for filing a notice of appeal must be made by written motion filed before the time for filing a notice of appeal has expired, except that such a motion filed not later than 20 days after the expiration of the time for filing a notice of appeal may be granted upon a showing of excusable neglect.

Here Unruh did not file a timely— or indeed any — written motion that requested an extension of time for filing her notice of appeal. In this instance the 20-day period allowed by Rule 8002(c)(2), which had to be measured from the February 23 deadline for the notice of appeal itself, ran out on March 15, 2004. And that failure on Unruh’s part is fatal to any argument based on “excusable neglect,” whether it is sought to be advanced under Pioneer Inv. or otherwise (In re Williams, 216 F.3d 1295, 1297-98 (11th Cir. 2000) (per curiam)).4

With all of that being true, the Kmart motion is plainly well taken. Unruh’s appeal and this action are dismissed with prejudice.
