April Fool's Day on a Saturday or a Sunday in the years 1975 - 1985?

[CdnWriter]

I am trying to find a year in the years of 1975 - 1985 where April Fool's Day arrived on a Saturday day or a Sunday day.

An adult is going to trick a child into pranking her parents by "pretending" to run away and she ends up abducted. I know HOW the kidnapper gets away and remains undiscovered, but I need a year to set this event in. My Google Fu is failing me - I'm 1,000% positive this information exists BUT.....WHERE????

I doubt it matters for this question but the child is 6 or 7, lives in the suburban part of a city.

Can anyone point me in the right direction? TIA!!!

We have fools on every day of the year.

Isn't "." the ISO delimiter to denote d m y dates? As in:

1.4.1978 is 4/1/1978 is 1978-04-01

They all get thrown around pretty randomly in the US, as if purely decorative.

The price of cultural diversity: calendar confusion.
