ORDER AND JUDGMENT *

Dale Armelin appeals from the district court’s dismissal of his complaint as untimely filed. We dismiss the appeal under 28 U.S.C. § 1915(e)(2)(B)(i) as frivolous.

I

Armelin filed suit against his former employer, the United States Postal Service, alleging race and color discrimination, and retaliation during his employment. *761 Defendants moved to dismiss the complaint for failure to state a claim under Fed.R.Civ.P. 12(b)(1) and 12(b)(6), arguing that Armelin had failed to exhaust and that the complaint was untimely filed. Armelin admitted in his response that his complaint was untimely because he wrote down the wrong deadline on his calendar.

A magistrate judge recommended that the motion to dismiss be granted, concluding that the complaint was untimely and that Armelin was not entitled to equitable tolling. Armelin filed objections to the recommendation, but he did not challenge the basis of the recommendation or the magistrate judge’s equitable tolling conclusion. The district court summarily adopted the magistrate judge’s recommendation and dismissed the complaint. It also denied Armelin’s request to proceed in forma pauperis (“IFP”), holding that an appeal would not be taken in good faith. Armelin appeals.

II

We conclude that Armelin has waived the arguments he seeks to advance on appeal by failing to present those arguments in his objections to the magistrate judge’s recommendation. “[W]e have adopted a firm waiver rule when a party fails to object to the findings and recommendations of the magistrate.” Duffield v. Jackson, 545 F.3d 1234, 1237 (10th Cir. 2008) (quotation omitted). “The failure to timely object to a magistrate’s recommendations waives appellate review of both factual and legal questions.” Id. (quotation omitted). “There are two exceptions when the firm waiver rule does not apply: when (1) a pro se litigant has not been informed of the time period for objecting and the consequences of failing to object, or when (2) the interests of justice require review.” Id. (quotation omitted). Neither exception applies in this case.

Armelin argued in his objections that his complaint had merit. But he did not present any argument challenging the magistrate judge’s analysis or recommendation as to timeliness and equitable tolling. (Nor could he, given his concession that he had simply made a mistake about the filing deadline.) By failing to object to the basis of the magistrate judge’s recommendation for dismissal, Armelin has waived our review. See Gardner v. Galetka, 568 F.3d 862, 871 (10th Cir. 2009).

Ill

Because Armelin has not advanced a reasoned, non-frivolous argument on appeal, the appeal is DISMISSED, 28 U.S.C. § 1915(e)(2)(B)(i), and we DENY his motion to proceed IFP, see DeBardeleben v. Quinlan, 937 F.2d 502, 505 (10th Cir. 1991).
