The Paraguay time difference is −3 hours from London and +2 hours from New York in winter, and −4 hours and +1 hour in summer (UK and US daylight saving seasons).
In practice, when it is noon in London it is 09:00 in Asunción during UK winter time (GMT) and 08:00 during British Summer Time. When it is noon in New York, it is 14:00 in Asunción during Eastern Standard Time and 13:00 during Eastern Daylight Time. Be careful: many guides still show a clock change in Paraguay or an older gap. That is no longer the case since October 2024: the country adopted UTC−3 all year round.

The one-hour difference between winter and summer comes only from the clock changes in the UK and the US: Paraguayan time no longer moves.
Why Paraguay no longer changes its clocks
Until 2024, Paraguay alternated between UTC−4 in the southern winter and UTC−3 in the southern summer: Law No. 7115 of 2023, still available on the website of the Paraguayan Congress library, set these two schedules. In October 2024 a new law (No. 7354/2024) made summer time permanent. According to the notes in the IANA database, it was promulgated on 11 October 2024 and published in the official gazette on 14 October 2024; the IANA database applies UTC−3 with no clock change since 15 October 2024. A proposal to return to two schedules was discussed in Parliament in 2025 without, to our knowledge, being adopted: check the local time before an important appointment.

Because Paraguay is on “summer” time all year, the sun rises late in the southern winter: around 07:33 in mid-June, with sunset around 18:07. Days range from 10 h 35 (June) to 13 h 42 (December). For a visit to the Jesuit missions or a walk along the Costanera, the late-afternoon light is therefore later than you might expect in winter. In London time, the mid-June sunrise in Asunción falls at 11:33 and the sunset at 22:07.
When to call Paraguay from the UK or the US
To reach someone between 09:00 and 20:00 Asunción time, call between 12:00 and 23:00 London time in UK winter, and between 13:00 and 00:00 (starting the evening before, local time) during British Summer Time. From New York, call between 07:00 and 18:00 during EST, and between 08:00 and 19:00 during EDT.
Time difference and jet lag: practical tips
Flying to Paraguay from the UK means travelling west: your day is lengthened, so you will need to go to bed later than usual. From the US East Coast the gap is only 1 to 2 hours eastwards. A few simple rules help you adjust to local time:
- Set your watch and phone to local time as soon as you board.
- Align meals and bedtime with local time from the first day.
- Plan a light first day, with no long road trip: the UK FCDO notes that driving on country roads at night can be particularly dangerous (GOV.UK, updated 3 November 2026).
- Get out in daylight when you arrive and avoid long naps.
- If you take medication at fixed times, ask your doctor how to adapt the schedule to the time difference.
- Check that your phone shows UTC−3: an old device that has not been updated may still apply the former rule.
