Zeuses,
Bless this day
Here is your natal from two perspectives, whole sign houses and Placidus. With Manchester’s latitude of 53°30' N, there are significant differences in house cusps.

Saturn in the 7th (whole signs) is very different from Saturn in the 6th (Placidus).
The date for Imgur chart which you posted shows transits and progressions for 12 April 2020.

Today is 4 August, so here you can see the changes which have occurred.

With Secondary Progressions everything is at a virtual standstill. I’ve been doing astrology since 1983, and gave up on Secondaries a long time ago, and also adopted whole sign houses 20 years ago.
Transiting Jupiter, Saturn, Uranus, Neptune, and Pluto are in the same house.
Because Venus went through retrograde, it is/was in 10th House from April 1, 2020 and enters the 11th on August 15 , 2020.
Transiting Mars is about to do something similar. On June 28, 2020, it entered Aries while it was in the 8th House. On August 13, 2020, it enters the 9th House. On September 9, it goes retrograde and remains in Aries until January 6, 2021.
Because the size of the 9th House is 34°39'55" with the Crapcidus house system, Mars remains in the 9th until February 28, 2021.
To return to your original question, the length of time which a planet spends in a house can be quite variable, especially with a house system such as Placidus. The size of your 7th House is 20°08'14", so transiting Mars was there from May 22, 2020 til June 22, 2020.
One month in the 7th House versus 119 days in the 9th (6 months, 15 days).
