Over the past 45 years I have own several lawn mowers. The first mower was purchased in 1972 from Sears and the latest mower is a Cub Cadet purchased in the fall 2022.
Currently I own three mowers.
In 2023, trying second and fourth week of the month mowing cycle at 3.5" height with trimming on the third week of the month. When there is 5 weeks in the month it gets a little long in the 3 week gap between the 4 and second week of the month but not impossible to mow.
Generally mowing season starts in May when soils warm enough for plants to grow and ends the second week in July when it starts to dry for the summer. If I use the twice a month scheduling that equals 5 times.
