Factor 1 - Launch Trajectory: The launch trajectory of Aditya-L1 is pivotal in determining its travel time. Utilising the Geosynchronous Satellite Launch Vehicle (GSLV) from India's Satish Dhawan Space Centre, the trajectory will leverage gravitational assists to reduce travel time.

Factor 2 - Distance to the Sun: Aditya-L1 must traverse the vast expanse between Earth and the Sun, averaging a staggering 93 million miles (150 million kilometres). The elliptical orbit of Earth introduces variability in this distance.

Factor 3 - Speed of the Spacecraft: Aditya-L1's velocity is a critical factor in determining travel time. Propelled by its onboard propulsion system, the spacecraft gradually increases speed, influenced by mission requirements and chosen trajectory.

Factor 4 - Gravity Assists: Harnessing gravity assists from celestial bodies like the Moon or planets accelerates Aditya-L1, reducing travel time. Precisely planned flybys strategically utilise gravitational pulls to propel the spacecraft towards its destination.

Estimated Travel Time: While exact travel time remains elusive without mission specifics, drawing parallels with NASA's Parker Solar Probe offers insights. The Parker Solar Probe, a comparable solar mission, took roughly 6 months to reach its first Sun close approach.

Considering technological strides and Aditya-L1's mission objectives, a comparable or slightly extended travel time is a reasonable expectation.
