Events preceding the murders on the night of 15–16 May 2008^[5][6][7]

Time	Activities
Before 9 pm (15 May)	On 15 May 2008, Nupur Talwar worked at her Hauz Khas clinic during 9 am-1 pm. She then picked up Aarushi from school at 1:30 pm, and returned to their Jalvayu Vihar apartment. Nupur's sister-in-law Vandana Talwar (wife of Rajesh's brother Dinesh) joined them for lunch. Then Nupur and Vandana left, while Aarushi stayed at home. Nupur then worked at the Fortis Hospital from 4:30 pm to 7:00 pm. She returned to the apartment around 7.30 pm. Rajesh Talwar taught at the ITS Dental College from 8:45 am to 3:30 pm, and then attended patients at the Hauz Khas clinic till 8:30 pm.
9 pm - 10 pm	Rajesh and his driver Umesh Sharma returned to Jalvayu Vihar around 9.30 pm. Umesh dropped Rajesh in front of the apartment building, and then drove away to park the car at the house of Nupur's parents, which was located at a walking distance (the Talwars did not have agarage). Umesh returned to the Talwar residence around 9:40 pm to hand over the car keys and Rajesh's bag to Hemraj, who had cooked the dinner for the family. Umesh saw Nupur and Aarushi near the dining table, and also Rajesh coming out of his bedroom. He was the last known outsider to see Aarushi and Hemraj alive.[8]
10 pm - 11 pm	According to the Talwars, after the dinner, they went to Aarushi's room, and gave her a Sony DSC-W130 digital camera.[9] The camera had arrived earlier that day via courier, and had been received by Hemraj. Rajesh had originally planned to give it to Aarushi on her birthday (24 May), but Nupur persuaded Rajesh to give it to Aarushi that day as an early birthday surprise. Aarushi clicked several photographs of herself and her parents, the last one at 10:10 pm. Subsequently, Aarushi's parents retired to their room, while Aarushi remained in her room.
11 pm-12 am	According to the parents, around 11 pm, Rajesh asked Nupur to switch on the internet router, which was located in Aarushi's room. When Nupur came to Aarushi's room, the teenager was readingChetan Bhagat's The 3 Mistakes of My Life. Nupur switched on the router and returned to her own room. Around this time, Rajesh answered a call from the US on the landline phone (kept in the couple's room). This indicates that the ringer was not silent. Rajesh then surfed some stock market and dentistry websites, and also sent an e-mail.[10] He visited an e-mail site at 11:41:53 pm: this is time when the desktop and the laptop show the last internet usage.[11]
After 12:00 am (16 May)	Around midnight, Aarushi's friend tried calling her on her mobile as well as the Talwar residence's landline. However, the calls were not answered. Around 12:30 am, he sent her an SMS message: this message was not received by Aarushi's phone.[10] The Internet router was used for the last time at 12:08 am.[12] Based on this, CBI inferred that Rajesh was online until 12:08 am.[13] The exact sequence of events between the midnight and 6:00 am could not be determined by the investigators with certainty (see conjecture below). According to their post-mortem reports, both Aarushi and Hemraj were killed somewhere between 12:00 am and 1:00 am.
