Breaking one's fast according to the sunset time mentioned on apps and websites
Q: I’m fasting. I try to follow the most accurate sunset times. Of course these different sites and apps make estimates of what sunset time is. For e.g, today one would said sunset is at 3:53, another two said 3:54 and another site said 3:55. I naturally would follow the latest one as a precaution, but nevertheless, would it be permissible to follow the earliest time?
