Recently due to COVID-19 outbreak, India prime minister Narendra Modi declared "Janatha Curfew" on March 22 2020 (sunday). Even Indian Railways won't run. How to travel long distance in India during "Janatha Curfew"?
Technically, if public trains and buses (or planes ?) are not operating, your options are limited.
I you are not part of an essential service, the only valid answer is stay home.
Respect the curfew. If you don't you might get arrested or fined and told to go back home.
If you are part of the essential services, you should ask the relevant authorities how would it be possible to travel on that day, and if you can do your travel on Saturday instead (for example if you absolutely need to be somewhere on Sunday).
For example, if you are a medical doctor and need to go somewhere, there might be private buses/shuttles to move essential personel around the country, and will probably be controlled to make certain no one with signs of the virus gets on board.
