¶1Dexter Bright has appealed from a judgment of sentence imposed following conviction in a bench trial for robbery,
¶2Appellant was arrested on March 14, 1979, and a complaint was filed against him the following day, March 15, 1979. Pursuant to Rule 1100(a)(2),
¶3“In reviewing the lower court’s ruling that the Commonwealth has or has not met its burden of proving due diligence, we may consider only the evidence presented at the hearing by the Commonwealth and that evidence presented by the defendant which remains uncontradicted.” Commonwealth v. Sharp, 287 Pa.Super. 314, 317, 430 A.2d 302, 304 (1981). Accord Commonwealth v, Ehredt, 485 Pa. 191, 194, 401 A.2d 358, 360 (1979); Commonwealth v. Mitchell, 472 Pa. 553, 564, 372 A.2d 826, 831 (1977); Commonwealth v. Jackson, 269 Pa.Super. 249, 253 n.4, 409 A.2d 873, 875 n.4 (1979). Appellant offered no evidence at the hearing, and the Commonwealth offered into evidence the record containing the notations made by the trial judge at the two previous listings of the case for trial. The record disclosed that on August 9, 1979, the complainant was on vacation, and that on September 4, 1979, the arresting officer was also on vacation.
¶4In Commonwealth v. Postell, 280 Pa.Super. 550, 552, 421 A.2d 1069, 1070 (1980), the appellant argued that the lower *102court had erred in accepting court records as evidence in a Rule 1100(c) hearing to extend. This Court dismissed the argument, noting that the use of notations in court records had been permitted in Commonwealth v. Gibson, 248 Pa.Super. 348, 375 A.2d 132 (1977) and Commonwealth v. Kollock, 246 Pa.Super. 16, 369 A.2d 787 (1977). See also Commonwealth v. Jackson, supra, 269 Pa.Super. at 253-254, 409 A.2d at 875. Similar records were properly received and considered by the court in the instant case.
¶5It is beyond peradventure that “ ‘[a] court may grant the Commonwealth an extension of time for trial if it finds that trial cannot be commenced within the prescribed period despite due diligence by the Commonwealth.’ Pa.R.Crim.P. 1100(c).” Commonwealth v. Sharp, supra 287 Pa.Super. at 317, 430 A.2d at 304 (1981), quoting Commonwealth v. Miller, 270 Pa.Super. 178, 182, 411 A.2d 238, 240 (1979). In the instant case, the delays on August 9, 1979 and September 4, 1979 were occasioned by the unavailability of the Commonwealth’s witnesses due to their respective vacation schedules. “[W]hen witnesses become unavailable toward the end of the Rule 1100 time period—whether through vacation, illness, or other reasons not within the Commonwealth’s control—the Commonwealth is prevented from commencing trial within the requisite period despite its due diligence and an extension of time is warranted.” Commonwealth v. Sharp, supra 287 Pa.Super. at 317, 430 A.2d at 304, quoting Commonwealth v. Sinor, 264 Pa.Super. 178, 183 n.5, 399 A.2d 724, 727 n.5 (1979) (emphasis added). This Court has repeatedly held that where delay in the commencement of trial is caused by the unavailability of a witness rather than by a lack of due diligence on the part of the Commonwealth, an extension under Rule 1100(c) is properly granted: Commonwealth v. Thompson, 292 Pa.Super. 108, 111-112, 436 A.2d 1028, 1030 (1981); Commonwealth v. Long, 288 Pa.Super. 414, 432 A.2d 228 (1981); Commonwealth v. Schuster, 288 Pa.Super. 310, 431 A.2d 1063 (1981); Commonwealth v. Sharp, supra 287 Pa.Super. at 318, 430 A.2d at 304; Commonwealth v. Coleman, 280 Pa.Super. 162, 164, 421 A.2d 455, *103456 (1980); Commonwealth v. Brant, 272 Pa.Super. 135, 141, 414 A.2d 707, 710 (1979); Commonwealth v. Sinor, supra 264 Pa.Super. at 183 n.5, 399 A.2d at 727 n.5; Commonwealth v. Brown, 252 Pa.Super. 365, 369, 381 A.2d 961, 963 (1977).
¶6Moreover, the initial delay in the instant case was caused by a defense requested continuance. “[D]efense-requested continuances may realistically obstruct diligent efforts by the Commonwealth to try an accused and may, therefore, justify an extension under Rule 1100(c).” Commonwealth v. Brant, supra 272 Pa.Super. at 140-141, 414 A.2d at 709, quoting Commonwealth v. Mancuso, 247 Pa.Super. 245, 253-254, 372 A.2d 444, 448 (1977). Accord Commonwealth v. Hill, 290 Pa.Super. 399, 403, 434 A.2d 813, 815 (1981); Commonwealth v. Garnett, 258 Pa.Super. 115, 120, 392 A.2d 711, 713 (1978); Commonwealth v. Brown, supra 252 Pa.Super. at 368-369, 381 A.2d at 963; Commonwealth v. Gibson, 248 Pa.Super. 348, 352, 375 A.2d 132, 133 (1977). Although it cannot be said that the defense continuance prevented trial within the period allowed therefor by Rule 1100, it may be observed. that such continuance did delay trial until the traditional summer vacation period. Thus, it could be considered by the court in determining whether the Commonwealth had exercised due diligence.
¶7This is not a case involving the concept of judicial delay. Therefore, we find it unnecessary to discuss the circumstances under which judicial delay will warrant the granting of an extension under Commonwealth v. Mayfield, 469 Pa. 214, 364 A.2d 1345 (1976). The only issue in this case is whether the Commonwealth exercised due diligence in commencing trial.
¶8Appellant’s trial date, as set by the court, was twenty-two days beyond the original amended run date under Rule 1100.
¶9The judgment of sentence is affirmed.
¶10. 18 Pa.C.S. § 3701.
¶11. 18 Pa.C.S. §§ 903, 3701.
¶12. 18 Pa.C.S. § 2701.
¶13. Rule 1100(c) provides:
*100(c) At any time prior to the expiration of the period for commencement of trial, the attorney for the Commonwealth may apply to the court for an order extending the time for commencement of trial. A copy of such application shall be served upon the defendant through his attorney, if any, and the defendant shall also have the right to be heard thereon. Such application shall be granted only if trial cannot be commenced within the prescribed period despite due diligence by the Commonwealth. Any order gra iting such application shall specify the date or period within which trial shall be commenced.
¶14. Rule 1100(a)(2) provides:
(2) Trial in a court case in which a written complaint is filed against the defendant after June 30, 1974 shall commence no later than one hundred eighty (180) days from the date on which the complaint is filed.
¶15. Rule 1100(d) provides:
(d) In determining the period for commencement of trial, there shall be excluded therefrom such period of delay at any stage of the proceedings as results from:
(1) the unavailability of the defendant or his attorney;
(2) any continuance in excess of thirty (30) days granted at the request of the defendant or his attorney, provided that only the period beyond the thirtieth (30th) day shall be so excluded.
¶16. Although the record may not be complete, it does not reflect that either appellant or his counsel made any objection when the court announced a new trial date beyond the Rule 1100 run date. This case was briefed and submitted before the Supreme Court’s decision in Commonwealth v. Brown, 497 Pa. 438, 438 A.2d 592 (1981), and the issue of waiver has not been discussed. Our decision on appeal, therefore, is not based upon appellant’s apparent failure to object to the October 23rd trial date set by the court.
¶17. The dissent would set aside the conviction for robbery and discharge appellant because, it contends, the Commonwealth failed to demonstrate that it had exercised due diligence between September 4 and October 1. It is not at all clear, however, what the representatives of the Commonwealth should have done to overrule the trial *104court and reschedule appellant’s trial after the court, on September 4, had specifically set October 23 as the date for the continued trial. It would seem that the District Attorney acted reasonably and with due diligence when he took the only practical step available. He asked the court to extend the time for commencement of trial to accommodate the trial date set by the court.
