had passed

[Ju]

For example:

Today is Jan 3, Jo's mum died on Jan1.
To make a sentence, I choose not to mention the date , can I say,

1. Jo's mum had passed away.
2. Jo's mum has passed away.
3. Jo's mum passed away.

To make a sentence, I choose to mention the date , can I say,

1. Jo's mum had passed away on Jan1.
2. Jo's mum has passed away on Jan1. .
3. Jo's mum passed away on Jan1.

Thanks.

All can be correct, depending on context.

Jo's mum has passed away on Jan1.

I don't like that one very much. We don't normally use a present perfect when a past time is specified, though you will hear it. In speech we often start a sentence, and then add something that we hadn't intended to say when we started.
