How do I transfer Notes + Calendar (iPhone) info onto Android phone?

[defmuse]

I've been an Apple user since the late 90's, and have never used an Android-based phone ever.

I finally gave up on Apple, and picked up the Xiaomi POCO F1 phone.

Please keep in mind that i know nothing about the Android OS. I'm slowly learning.

I used to have an iPhone 6, and had a whole bunch of notes, calendar information, and voice notes/recordings on it.

The obstacles 'm currently facing:

1. All my notes (from my previous iPhone) were saved on my GMAIL account... i can see them in the "Notes" section. I've synched my google account with my POCO, but the notes have not transferred over. Is there a convenient way to transfer/sync my Notes saved on Gmail onto my POCO phone?

2. Same question regarding my previous iPhone calendar info being transferred onto my Calendar on my Android phone...?

Thank you in advance for your advice, suggestions, and help.
