How to change delivery date on amazon india?

I can help with this. It is simple sometimes. First, go to your Amazon account. Then, you click on "Your Orders". Find the order you want to change.

Look for an option that says "Change delivery date". You will only see this if your package has not shipped yet. If you see it, you can click it and pick a new day from the calendar.

If you don't see the option, sorry, it is too late to change. It means the item is already getting ready to ship. I hope this is helpful for you.
