Abstract : The primary objective of this study is to investigate the timing properties and behavior of the quasi-periodic oscillations (QPOs) in GX 339-4 during the 2021 outburst. The Modified Julian Dates (MJDs) for the outburst, specifically MJD 59250-59500, were determined utilizing the MAXI on-demand process. The study utilizes data from the Neutron Star Interior Composition Explorer (NICER) and employs the General High-Energy Aperiodic Timing Software (GHATS) for temporal analysis. The observations used in this study are chosen with ~20 days separation over the whole span of the outburst to check the variability in the QPOs. By analyzing the QPOs, valuable insights into their characteristics and origin has been obtained. The analysis involve examining the frequencies, amplitudes, and changes in the QPOs' properties throughout the outburst.
