The date of Tihar falls in either in October or November (Kartik or Mangsir) each year, depending on the cycle of the moon. The Tihar festival actually runs for five days, beginning with Kaag Tihar, although the main celebrations (Laxmi Puja) happen on the third day of Tihar.
Tihar always ends with Bhai Tika, fifth day of Tihar. Tihar in 2018 will start on Wednesday, the 21st of Kartik and will continue for 3 days until Thursday, the 23rd of Kartik. The two days of Tihar often fall before the main day of Tihar, Laxmi Puja (7th October). According to Nepali Calendar, Tihar in 2075 (Laxmi Puja in 2075 B.S.) will start on Thursday, Kartik 21.
The important tihar date is bhai tika. It is celebrated on 9th of October, 2018 this year. The Nepali date of Bhai tika is 23rd of Kartik, 2075. So, the tihar tika time will be on 23rd of Kartik, 2075.
