Sunrise 3.0 FAQ
A. The 1 minute difference may actually be as little as 1 second in the computations, but magnified when rounded up/down to the nearest whole minute (we discussed returning seconds in timestamps, but as we feel the algorithms aren’t precise enough it’s better to round off).
A. We have decided to return only one day per request, both to optimize caching but also keep the response time as low as possible. Since the calculations are quite CPU intensive, a 7-day forecast might cause unacceptably high response times and impact other services on the API. This is also why the sun and moon events are separate requests, as many don’t need the latter and it’s a waste of resources.
