Tells you when the next poya day is. https://nextpoyawhen.com

Poya occurs every full moon day. It's a public holiday in Sri Lanka, so everyone here loves when it's Poya.

You can get the JSON array of poya days from the endpoint https://nextpoyawhen.com/poya.json

After making changes to index.html or poya.json, run ./replace.sh to update the poya days array. It will overwrite the index-stage.html file. This latter HTML fie is what you should run in the browser.

To automatically replace when index.html is updated, use a command like fswatch:

fswatch index.html | xargs -n1 -I{} ./replace.sh

To deploy the changes to S3, run ./deploy.
