Fewer planes on Saturdays?

[Easton S]

Hi,

I'm quite new to monitoring planes, so please excuse me if my question is naïve - I've tried looking for an answer already, but haven't found anything. I've been tracking ADS-B transmissions for almost a month now and I've noticed that on every Saturday, there seems to be fewer planes being observed, whilst Sunday has about the same amount of traffic as every other day of the week.

Is there any particular reason for this dip in plane traffic on Saturdays? Viewing other Sydney feeders' ADS-B statistics on FlightAware shows a similar dip on Saturdays, so it doesn't appear to be something localised to my location.

Thanks .
