Why Armenia no longer changes its clocks
Armenia applied daylight saving time until 2011. On 9 February 2012 the National Assembly adopted in final reading amendments to the law on the calculation of time on the territory of the Republic of Armenia that abolish the switch to summer time. Since then the country has stayed on UTC+4 all year. The IANA time zone database, used by computers and phones, records this rule: the last seasonal change dates from October 2011.

When to call Armenia from the UK or the US
To reach someone between 09:00 and 20:00 Yerevan time, call between 05:00 and 16:00 London time in UK winter, and between 06:00 and 17:00 during British Summer Time. From New York, call between 00:00 and 11:00 during EST, and between 01:00 and 12:00 during EDT.
Time difference and jet lag: practical tips
Flying to Armenia from the UK or the US means travelling east: your day is shortened by 3 to 4 hours from London and by 8 to 9 hours from New York. The gap from the UK is moderate, but a few rules help you adjust:
- 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 says the standard of driving in Armenia is poor and advises avoiding driving outside cities and towns in the dark because of the condition of the roads and the lack of lighting (GOV.UK, updated 1 March 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.
