Prayer Times in Round Rock, TX

Times are calculated using astronomical algorithms based on Round Rock's exact coordinates (30.5083°, -97.6789°) and time zone (America/Chicago). Accuracy is typically within 1-2 minutes. Calculation uses the ISNA method (15° Fajr/Isha angles), which is the standard for North American Muslim communities.

From Round Rock, the Qibla bearing is approximately 43° (northeast) from true north. This is the great-circle bearing toward the Kaaba in Mecca (21.4225°N, 39.8262°E). Use a phone compass or Qibla-finder app, calibrated for magnetic declination, for precise alignment.

The fast length depends on when Ramadan falls in the lunar calendar relative to the solar year. In Round Rock, the longest possible Ramadan fast (summer) is approximately 14h 0m, while the shortest (winter) is around 10h 0m. The Islamic year is ~10-11 days shorter than the solar year, so Ramadan shifts earlier each Gregorian year.

We use the ISNA (Islamic Society of North America) method with 15° angles for both Fajr and Isha. This is the most widely-followed standard in North America. Other methods (MWL, Egyptian, Karachi, Umm al-Qura) use different angles and may produce times 5-15 minutes apart. Confirm with your local mosque if they prefer a different method.

Yes. All times are shown in Round Rock's local time (America/Chicago) and automatically adjust for Daylight Saving Time changes (second Sunday in March, first Sunday in November). The actual position of the sun does not change — only the clock face.

Jumu'ah typically takes place during the Dhuhr window. The times shown here are the start of Dhuhr; your local mosque in Round Rocksets the actual khutbah and salah time, often 15-45 minutes after Dhuhr begins. Check your mosque's schedule directly.
