This is an appeal from judgment of sentence for driving under the influence of alcohol. 1 Appellant argues that the trial court improperly grantеd the Commonwealth’s petition for an extension of time under Pa.R.Crim.P. 1100. We agree and therefore reverse the judgment of sentence and dischargе appellant. 2
The criminal complaint was filed on March 1, 1982. After a preliminary hearing on April 6, 1982, appellant was held over for court. A member of the District Justice’s staff misfiled the papers on appellant’s case; instead of transmitting them to the County Clerk of Court, she filed them in the “closed file.” N.T. 12/13/82, 11. In November 1982 appellant’s counsel happened to meet the police officer who had filed the complaint. Counsel asked the officer about the case. The officer said he would check into it, and telephoned the District Attorney’s office, to be told that the pаpers had never been received, N.T. 12/13/82, 6-7.: 3 On November 12, 1982, a member of the District Attorney’s office called the District Justice’s office, and, upon learning about the misfiling, directed that the papers be sent to the courthouse immediately. N.T. 12/13/82, 12. On November 15, 1982, the complaint and transcript were filed. On November 30, 1982, 4 the Commonwealth filed a petition for an extension of time under Rule 1100, identifying the source of the delay and alleging its “due diligence.” Appellаnt filed an answer and moved for a dismissal of the charges against him. The trial court denied appellant’s *12 motion and granted the petition for an еxtension. Appellant was tried and convicted, and after being sentenced, took this appeal.

A petition for an extension of time must be filed “prior to the expiration of the period for commencement of trial.” Pa.R.Crim.P. 1100(c)(1). The “period for commencement of trial” is 180 days. Pa.R.Crim.P. 1100(a)(2). In counting these 180 days, certain days are excluded. Pa.R. Crim.P. 1100(d). Specifically, “there shall be excluded”: the period between the filing of the comрlaint and the defendant’s arrest, where the defendant’s whereabouts were unknown and could not be determined by due diligence; any period for which the defendant waives the rule; and such period as results either from the unavailability of the defendant or his attorney, or from a continuance grantеd at the request of the defendant or his attorney.
Id.
Here, there was no period fitting any of these categories. The only period in question was thе period from April 6, 1982 (the date of the preliminary hearing) to November 12, 1982 (the date the District Justice’s office discovered that the papers hаd been misfiled). This period may not be excluded — nor does the Commonwealth claim that it may be — for judicial delay

is not excludable under Rule 1100(d).
Commonwealth v. Shelton,
-2-
The Commonwealth argues that its petition for an extension of time was properly granted because it еxercised “due diligence.” This argument, however, is not available to the Commonwealth.
Commonwealth v. Lamonna,
Even if the Commonwealth did have available the argument that it exercised due diligence, we should find the
*14
argument without merit. It was the Commonwealth’s burden to prove due diligence in thе prosecution of appellant.
See Commonwealth v. Jones,
Judgment of sentence reversed and appellant discharged.
Notes
. 75 Pa.C.S. § 3731. The offense occurred prior to the effective date of the amendment of this provision. Act of Dec. 15, 1982, P.L. 1268, No. 289, § 9, effective in 30 days.
. Because we agree with appellant’s Rule 1100 argument, we do not reach his other arguments.
. No one from the District Attorney's office testified at the hearing оn the petition to extend. The record therefore does not disclose what procedure, if any, was followed for keeping track of сases held over for court. The docket entries for the preliminary hearing do not indicate that an attorney for the Commonwealth was prеsent.
. The petition is dated November 23, 1982, but the date of filing stamped on the petition is November 30, 1982, and the docket entries confirm the 30th as the date оf filing.
. The Commonwealth concedes that this period was a period of judicial delay, characterizing it as the result of, the “oversight ... of the judiciary.” Brief for Appellee at 7. This was also the trial court’s characterization. Opinion and Order Sur Commonwealth’s Petition for Extension of Time, 12/23/82, at 4.
. The Commonwealth alleged in its petition for an extension of time, and the trial court found, that the period ended August 26, 1982. Petition, para. 4; Opinion and Order Sur Commonwealth’s Petition for Extension of Time, 12/23/82, at 2. According to our calculations, August 26 was the 178th day, and, because the 180th day fell on a Saturday, the run date was August 30, 1982. However, this discrepancy does not affect the analysis in any way.
