Airport: Dushanbe Airport (DYU) is 1 mile (2km) south of the city. Bus nos. 3 and 12, and trains 3 and 4, run to the city centre 0600-1800 (travel time - 20 minutes).
Climate: In Dushanbe, temperatures vary between a minimum -13°C (8°F) in December/January to a maximum 33°C (91°F) in July/August
Visa and LOI to Tajikistan: I am a citizen of EU, but my boy-friend is Japan, so not to risk and avoid the problems on the border, we made our visas in advance by 12 euros per person through http://www.tajikistanvisa.land.ru/
Special Events : There is a carnival of Navruz (the beginning of the Persian New Year), when a special dish called sumalak is prepared from germinating wheat. Other events celebrated are tied to the Muslim calendar.
Social Conventions : Lipioshka (bread) should never be laid upside down, and it is normal to remove shoes, but not socks, when entering someone’s house. Shorts are rarely seen in Tajikistan and, worn by females, are likely to provoke unwelcome attention from the local male population.
Favorite thing: The best thing about Dushanbe in terms of money? There are easy exchange possibilities through perfectly legal cash exchange counters along Rudaki avenue and through ATMs in hotels and at banks. Same situation in Khojand. No problem at all until you try to get money at some remore location outside Dushanbe.
The best times to visit Dushanbe is March-April and October-November to avoid the worst heat and the coldest temperatures.
