Salams,

Thank you so much for providing this API. May your efforts be rewarded insh!
I'm using the from/to endpoint: https://aladhan.com/prayer-times-api#get-/calendar/from/-start-/to/-end-

I have the following request:

curl -X GET "https://api.aladhan.com/v1/calendar/from/01-05-2023/to/05-05-2023?latitude=40.73061&longitude=-73.935242&iso8601=true" \
 -H 'accept: application/json'

For some reason, it returns results for 30-04-2023. Is this a bug?
