Drag on the grid to compare working hours visually: Click Select if needed, then drag across the Round Rock row from 9 AM to 11 AM Central Time to highlight a meeting window in purple. On a standard-time date, that same window appears as 10 AM to 12 PM in New York, 3 PM to 5 PM in London, and 12 AM to 2 AM the next day in Tokyo, which quickly shows that a Round Rock morning meeting works well for the US and UK but not for East Asia.
Export the selected time for your team or clients: After selecting a range, use the export options shown on the page: ICS download, Google Calendar, Gmail, Copy to clipboard, or Share link.

About Round Rock Time Zone
Round Rock uses the America/Chicago IANA time zone, the same time zone used by much of the US Central Time region. Its standard offset is UTC-6, and during daylight saving time it changes to UTC-5, displayed as Central Daylight Time (CDT). This matters for anyone planning calls, deliveries, or support coverage because the offset changes seasonally rather than staying fixed year-round.
Round Rock is located in Texas, just north of Austin, so it follows the same time rules as most of the state and the wider US Central Time Zone. In practical terms, Round Rock is typically 1 hour behind New York in the Eastern Time Zone and 1 hour ahead of Denver in the Mountain Time Zone. That positioning makes it a common bridge for companies coordinating work between the US coasts, especially in technology, manufacturing, healthcare, and customer support.
Daylight saving time in Round Rock follows the current US schedule: clocks move forward on the second Sunday in March and move back on the first Sunday in November. For 2025, DST begins on March 9, 2025, when clocks advance from 2:00 AM to 3:00 AM, and ends on November 2, 2025, when clocks return from 2:00 AM to 1:00 AM. If you are booking travel, webinars, or recurring meetings with people outside the US, these dates can shift the time difference by one hour compared with countries that change clocks on different weekends or do not use DST at all.
Round Rock City Details
Round Rock is a city in the US state of Texas with a population of 115,997, making it a significant part of the greater Austin regional economy. Its location at 30.50826°, -97.6789° places it in Central Texas, where it benefits from strong road access, proximity to Austin-Bergstrom International Airport, and close links to technology, education, retail, and healthcare employers in the Austin metropolitan area.
The local currency in Round Rock is the United States dollar (USD), which is used for all everyday transactions, salaries, hotel bookings, and business payments. The country dialing code is +1, so international callers reaching Round Rock from abroad use the US country code before the local number. These details are particularly useful for travel planning, supplier coordination, and international customer support operations.
Time Differences from Round Rock
Round Rock is in US Central Time, so its time difference with other cities depends on whether daylight saving time is active in both locations. During much of the year, the most common relationships are easy to plan around for meetings, trading windows, and travel itineraries.
- New York: Round Rock is 1 hour behind New York. When it is 9:00 AM in Round Rock, it is 10:00 AM in New York, which makes late morning on the East Coast a good overlap for calls with Texas-based teams.
- London: Round Rock is usually 5 or 6 hours behind London depending on DST alignment. On a typical summer date, when it is 9:00 AM in Round Rock, it is 3:00 PM in London; on some winter dates, it may be 4:00 PM in London if offset rules differ seasonally.
- Tokyo: Round Rock is generally 14 or 15 hours behind Tokyo depending on the US DST period. When it is 9:00 AM in Round Rock, it is usually 11:00 PM or 12:00 AM in Tokyo, so same-day live collaboration is limited.
- Sydney: Round Rock is commonly 15, 16, or 17 hours behind Sydney depending on the month because Australia and the US switch daylight saving on different calendars. When it is 9:00 AM in Round Rock, it is often 12:00 AM, 1:00 AM, or 2:00 AM the next day in Sydney, which usually pushes meetings toward Round Rock late afternoon instead.
- Dubai: Round Rock is typically 9 or 10 hours behind Dubai because Dubai stays on UTC+4 year-round while Texas changes for DST. When it is 9:00 AM in Round Rock, it is usually 6:00 PM or 7:00 PM in Dubai, making Round Rock mornings useful for same-day business communication with the Gulf region.
For practical scheduling, a 2 PM to 4 PM work block in Round Rock often aligns well with 3 PM to 5 PM in New York, 8 PM to 10 PM in London during part of the year, and 11 PM to 1 AM in Dubai or later depending on DST. That means Round Rock is well positioned for North American coordination, moderately workable for Europe, and much harder for East Asia and Australia unless one side accepts early-morning or late-night meetings.
Frequently Asked Questions
What time zone is Round Rock in?
Round Rock is in the America/Chicago time zone, which is the IANA name for the US Central Time Zone used by most of Texas. In everyday usage, this means Round Rock follows Central Standard Time (CST, UTC-6) in winter and Central Daylight Time (CDT, UTC-5) during daylight saving time.
Does Round Rock observe daylight saving time?
Yes, Round Rock observes daylight saving time under current US rules. Clocks move forward on the second Sunday in March and move back on the first Sunday in November; in 2025, that means DST starts on March 9 and ends on November 2. This seasonal shift affects meeting times with places that do not change clocks, such as Dubai, or that change on different dates, such as parts of Europe and Australia.
Time difference between Round Rock and New York?
Round Rock is normally 1 hour behind New York because Round Rock is in Central Time and New York is in Eastern Time. If it is 9:00 AM in Round Rock, it is 10:00 AM in New York, so a Round Rock team starting the workday can usually reach East Coast colleagues already in mid-morning. This small gap makes same-day collaboration easy for sales, legal, finance, and customer support teams.
Best time to call Round Rock from US/UK?
From elsewhere in the US, the best time to call Round Rock is usually during 9:00 AM to 4:00 PM Central Time, which corresponds to 10:00 AM to 5:00 PM in New York and 7:00 AM to 2:00 PM in Los Angeles during standard alignment. From the UK, the most practical overlap is often 2:00 PM to 5:00 PM London time for reaching Round Rock in the morning, or 4:00 PM to 6:00 PM London time if you want a later Texas business window. Because US and UK daylight saving changes happen on different dates, the exact difference can temporarily shift by one hour in March and late October.
What is the UTC offset for Round Rock?
Round Rock has a standard UTC offset of UTC-6 and a daylight saving offset of UTC-5. If you are entering the time into scheduling software, travel systems, or server logs, remember that the correct offset depends on the date you are checking, not just the city name. Using the America/Chicago zone identifier is more reliable than manually typing an offset because it automatically accounts for DST transitions.
What currency does Round Rock use?
Round Rock uses the United States dollar (USD), the official currency of the United States. This is relevant for travelers booking hotels, paying for transport, or estimating meal and retail costs, and for international businesses invoicing Texas-based customers or vendors. If you are calling from abroad, you will also use the US country code +1 when dialing Round Rock numbers.
Is Round Rock the same time as Austin, Texas?
Yes, Round Rock and Austin use the same time zone and daylight saving schedule because both are in Central Texas and follow America/Chicago. There is no local time difference between the two cities, so if a meeting is scheduled for 1:00 PM in Austin, it is also 1:00 PM in Round Rock. This is useful for travelers staying in one city and attending business, sports, or events in the other.
Why does the time difference between Round Rock and London sometimes change?
The difference changes because both the US and UK observe daylight saving time, but they do not switch on the same dates. Round Rock follows the US schedule, while London follows the UK/European schedule, so for a few weeks in spring and autumn the gap can be different from the usual pattern. This is a common source of missed meetings for remote teams, so checking the exact date on a visual converter is safer than relying on memory.
