Why Fajr and Isha need an estimation rule here
At this latitude the sun does not sink a full 18° below the horizon around midsummer, so true night — and with it the astronomical basis for Fajr and Isha — does not occur for several weeks. We apply the Middle of the Night rule during that period, splitting the interval between sunset and sunrise. Your local mosque in Greencastle may use a different convention; where they differ, follow the mosque.

Prayer times in Greencastle — common questions
What time is Fajr in Greencastle today?
Fajr in Greencastle begins at 01:33 AM today. Fajr starts at true dawn, when the sun reaches a set angle below the horizon, and ends at sunrise — so this time shifts by a minute or two each day as the season changes.
Which direction is the Qibla from Greencastle?
From Greencastle, the Qibla is 114.9° from true north — roughly ESE. Remember that a phone compass points to magnetic north, so you may need to correct for local magnetic declination.
Which calculation method is used for Greencastle?
These times use the MWL convention, which is the standard recognised across Ireland. If your mosque follows a different authority, its Fajr and Isha may differ by several minutes — the calculation is identical, only the twilight angle changes.
Are these times accurate for a place the size of Greencastle?
Yes. Prayer times are computed from Greencastle's own coordinates, not borrowed from a larger neighbouring city, so the astronomy is exactly as accurate as it is for a capital. The only caveat is that we use a single reference point for the settlement.
Do prayer times in Greencastle change much between seasons?
Considerably. With a 10.3-hour difference between the longest and shortest day, Fajr and Isha shift substantially across the year in Greencastle, while Dhuhr — tied to solar noon — barely moves. Checking weekly rather than monthly is worthwhile.
