What Permanent DST Means for Sunrise and Sunset in 2027
Starting November 2027, permanent Daylight Saving Time (DST) will shift sunrise in the continental U.S. one hour later than standard time, with December sunrises ranging from 7:50 AM in Los Angeles to 8:20 AM in New York City. Sunset will occur one hour later, extending evening daylight into the 5–6 PM hour during winter months.
This change prioritizes evening light at the cost of darker mornings—especially in western time zones. For example, Cody, Wyoming will see sunrise at 8:49 AM in December 2027, while Myrtle Beach, South Carolina will have sunrise at 8:20 AM and sunset at 6:06 PM. Hawaii and most of Arizona will remain on standard time, creating a permanent one-hour discrepancy with neighboring states on permanent DST.
Travelers must account for these time-zone differences when booking multi-city trips. Darker mornings may disrupt early-morning activities like ski resort operations or 7 AM meetings in cities like Chicago (sunrise: 8:15 AM in December). For winter travel, prioritize locations with later sunrises if morning activities are critical. For evening-focused trips, permanent DST extends usable daylight, benefiting nightlife destinations like Las Vegas (sunset: 5:50 PM in December).
| City | December 2027 Sunrise (Permanent DST) | December 2027 Sunset (Permanent DST) | Standard Time Sunrise (Current) |
|---|---|---|---|
| New York, NY | 8:20 AM | 5:30 PM | 7:20 AM |
| Chicago, IL | 8:15 AM | 5:25 PM | 7:15 AM |
| Los Angeles, CA | 7:50 AM | 5:45 PM | 6:50 AM |
| Phoenix, AZ | 7:20 AM (standard time) | 5:20 PM (standard time) | 7:20 AM |
| Cody, WY | 8:49 AM | 5:40 PM | 7:49 AM |
Which U.S. Regions Will Adopt Permanent DST—Worked example
Here’s how permanent Daylight Saving Time (DST) could impact your winter 2027 trip from Chicago (ORD) to Orlando (MCO). Book a Tuesday, December 14, 2027, departure with a Saturday, December 18 return, and you might see roundtrip prices on American Airlines drop to $215 for a red-eye flight (departing 10:30 PM, arriving 2:10 AM) due to lower demand for darker morning arrivals—compared to $298 for a 6:00 AM departure under current pricing. Hotels in Orlando, however, could cost 10–12% more for those same dates: a standard room at Disney’s Pop Century Resort might jump from $220/night to $245/night as extended evening daylight boosts demand for nighttime park visits. Action step: Use Google Flights’ "flexible dates" grid to compare red-eye vs. morning departure prices for this route in Q4 2026, when airlines start adjusting 2027 schedules.

and Which Won’t
The U.S. will adopt permanent Daylight Saving Time on November 3, 2027, if the Sunshine Protection Act remains law. Clocks will not revert to standard time, locking the country one hour ahead year-round. However, Hawaii, most of Arizona (excluding the Navajo Nation), and U.S. territories (Puerto Rico, Guam, etc.) will remain on standard time, creating a permanent one-hour mismatch with adopting states.
Key exceptions include:
- Arizona: Phoenix will stay on standard time (sunrise: 7:20 AM in December), while Tucson (100 miles away) will follow permanent DST (sunrise: 8:20 AM).
- Alaska: May split between UTC-8 (standard time) and UTC-9 (DST), resulting in intra-state time differences.
Travelers booking 2027 trips must verify time standards for each destination. Airlines are adjusting pricing now; travelers booking 2027 flights in the next 3–6 months (Q3–Q4 2026) will see schedule shifts reflected in fares. Use updated tools (e.g., Google Flights’ 2027 time-zone filter) and book DST-exempt regions (Phoenix, San Juan) 3–6 months in advance to avoid volatility.
| Region | Time Standard (2027) | Key Impact on Travel | Booking Tip |
|---|---|---|---|
| Continental U.S. (except AZ) | Permanent DST (UTC-4 to UTC-7) | Sunset 1 hour later; evening flight demand ↑3–5% | Book winter flights 6–7 months ahead |
| Arizona (most) | Standard time (UTC-7) | 1-hour gap with CA/NV; misaligned flight times | Add 1-hour buffer to Phoenix connections |
| Hawaii | Standard time (UTC-10) | No DST effect; pricing stable | Book anytime; no peak shifts |
| Alaska (proposed split) | UTC-8 (standard) or UTC-9 (DST) | Intra-state time differences (e.g., Anchorage vs. Juneau) | Confirm local time for each stop |
| U.S. Territories (Puerto Rico, Guam) | Standard time (UTC-4, UTC-10) | No DST; layovers may misalign with mainland | Check time zones for all legs |
How Flight Prices Will Shift in 2027—By Route and Time of Day
Permanent Daylight Saving Time will shift flight prices in 2027 by 3–15% depending on route, season, and departure time. Evening departures (4–8 PM) will rise due to extended usable daylight, while red-eyes (10 PM–6 AM) will fall as darker mornings reduce demand.
Airlines are adjusting pricing now; travelers booking 2027 flights in the next 3–6 months (Q3–Q4 2026) will see schedule shifts reflected in fares. Historical data from the 1974 DST trial showed a 3–5% increase in domestic flight prices, with leisure routes seeing the steepest hikes. Business routes may see smaller increases (2–4%), but red-eyes could drop 10–15% due to reduced overnight demand.
Seasonal variance will amplify effects. Winter 2027 (November–February) will see the largest swings, as permanent DST delays sunrise to 8:15–8:50 AM in major hubs. JFK-LAX red-eyes may see a 10–15% price drop in December 2027, while evening departures could rise by 5–7%. Summer 2027 will be less affected, but shoulder seasons (March–April, September–October) may see 5–8% increases for evening flights.
| Route Type | 2027 Price Shift (vs. 2026) | Peak Season | Best Booking Window |
|---|---|---|---|
| Leisure (e.g., NYC–Orlando) | +8–12% (evening) | Nov–Feb, Dec holidays | 6–7 months ahead |
| Business (e.g., SFO–SEA) | +2–4% (evening), -10–15% (red-eye) | Jan–Feb, Oct–Nov | 5–6 months ahead |
| Transcontinental (e.g., JFK–LAX) | +5–7% (evening), -12–18% (red-eye) | Dec–Jan | 7–9 months ahead |
| International (e.g., NYC–London) | -5–8% (winter) | Nov–Feb | 9–11 months ahead |
| Asia-bound (e.g., LAX–Tokyo) | +6–10% (year-round) | Mar–Apr, Sep–Oct | 10–12 months ahead |
Exceptions include DST-exempt regions. Flights to/from Arizona or Hawaii may drop 3–5% due to time-zone mismatches. International routes to Europe may become 5–8% cheaper in winter 2027 as U.S. time zones align closer to European daylight hours. Asia-bound flights could rise 6–10% due to exacerbated time differences.
Common mistakes to avoid:
- Booking red-eyes without checking adjusted departure times (some may shift to earlier evening slots).
- Assuming all states follow permanent DST (Arizona/Hawaii connections may list incorrect local times).
- Overlooking shoulder-season price hikes (March–April, September–October), which could add 10–15% to evening flights.
To lock in fares, book 5–7 months ahead for off-peak (Q1–Q2 2027) or 9–11 months for peak seasons. Target December–February for red-eyes (15–20% below 2026 levels). Avoid booking leisure routes (Florida, Vegas) in November–February without a price lock—fares could rise significantly due to increased demand.
How Hotel Rates Will Change in Winter 2027—By Destination Type
Winter 2027 hotel rates will rise 8–12% in leisure destinations and fall 5–7% in business hubs under permanent Daylight Saving Time. Extended evening daylight (sunset at 5:30–6:00 PM in December) increases demand for nightlife and outdoor activities, while darker mornings (sunrise at 8:15–8:20 AM) reduce early-morning business travel.
Leisure markets—Orlando, Las Vegas, Miami Beach—will see the steepest increases. Leisure destinations like Orlando and Las Vegas could see hotel rates rise by 8–12% in winter 2027 due to extended evening daylight. Business hotels in New York, Chicago, and San Francisco will face softer demand, with midweek discounts. Business hotels in Chicago may see midweek discounts of 5–7% for January 2027 stays.
DST-exempt regions (Arizona, Hawaii) will see stable rates, with Phoenix hotels potentially gaining 3–5% in winter bookings due to consistent sunrise times (7:20 AM). Ski resorts will see delayed lift openings (sunrise at 8:49 AM in Cody, WY) but higher rates due to extended après-ski revenue.
| Hotel Type | 2027 Winter Rate Change | Key Driver | Example Property |
|---|---|---|---|
| Leisure (Orlando, Vegas) | +8–12% | Extended evening daylight | Bellagio, Disney World Resorts |
| Business (NYC, Chicago) | -5–7% | Darker mornings, fewer meetings | Marriott Marquis, Hyatt Regency |
| DST-exempt (Phoenix, Hawaii) | 0–3% | No time change, stable demand | Royal Hawaiian, JW Desert Ridge |
| Ski resorts (Aspen, Park City) | +4–6% | Later sunrise delays lifts, extends après-ski | St. Regis Aspen, Montage Deer Valley |
Booking strategy:
- Secure leisure hotels 6–8 months in advance (by early 2027) to avoid hikes, or book now for winter 2026–2027 stays.
- Target January–February 2027 for business travel discounts (up to 10% for Tuesday–Thursday stays).
- Verify local sunrise/sunset times for trips involving Arizona or Hawaii.
The Best Booking Windows for 2027 Trips Under Permanent DST
Book 2027 flights 5–7 months in advance for domestic U.S. trips and 9–11 months ahead for international or peak-season travel. Airlines will adjust schedules and pricing 6–12 months before permanent DST takes effect in November 2027, with the most volatile fares appearing for trips departing December 2027–March 2028.
The 5–7 month window aligns with historical domestic trends, but permanent DST may require earlier booking for peak seasons (9–11 months ahead). For example, JFK-LAX flights in January 2027 may cost $287 round-trip if booked in August 2026, while Friday evening flights could rise to $412. International routes to Europe may become 5–8% cheaper in winter 2027 due to closer U.S.-Europe daylight alignment, but this advantage erodes if booked within 3 months of departure.
Exceptions apply to DST-exempt regions. Book flights to Hawaii, Arizona, or U.S. territories 7–9 months ahead, as these routes won’t experience DST-related demand shifts but may face misaligned connections. Alaska’s potential time-zone split (UTC-8 vs. UTC-9) adds complexity; book intra-state flights 8+ months ahead to avoid schedule conflicts.
What to do next
Permanent Daylight Saving Time in 2027 will reshape travel pricing—here’s how to prepare and lock in the best rates before shifts take effect.
| Step | Action | Why it matters |
|---|---|---|
| 1 | Check the U.S. Sunshine Protection Act status by Q1 2026 to confirm permanent DST adoption. | Passage triggers airline/hotel pricing adjustments 6–12 months in advance. |
| 2 | Book 2027 flights to leisure destinations (e.g., Orlando, Las Vegas) by Q2 2026 to avoid 8–12% winter rate hikes. | Extended evening daylight will spike demand for nighttime activities. |
| 3 | Verify red-eye flight prices for 2027 routes (e.g., LAX→JFK) in Q3 2026—expect 10–15% discounts. | Darker mornings reduce overnight travel demand, lowering fares. |
| 4 | Target Q1–Q2 2027 hotel stays in business hubs (e.g., NYC, Chicago) for 5–7% lower rates. | Darker mornings decrease early-morning meeting demand. |
| 5 | Compare flight prices to Hawaii/Arizona (exempt from DST) vs. mainland U.S. for stable alternatives. | These regions won’t adjust clocks, avoiding pricing volatility. |
| 6 | Lock in 2027 international flights to Europe by Q4 2026 to capitalize on 5–8% potential savings. | Permanent DST aligns U.S. time zones closer to Europe, reducing jet lag penalties. |
