September marks the end of summer and the beginning of autumn in Lithuania, with the associated traditional and cultural festivities. Here are some of the important festivals and celebrations in September: 
 

Traditionally known as Science and Knowledge Day, it is celebrated on the first of September to mark the start of the school year. Schools hold ceremonial line-ups as pupils and students return to their educational institutions after the summer holidays. 

The autumnal equinox is an astronomically important date when day and night become equal in length. Although it is not an official holiday, many nature lovers commemorate this day as the transition to the autumn season. 

European Heritage Days are celebrated in September, usually on the second weekend. This is an opportunity to visit museums, castles, manor houses and other cultural sites, which often open their doors for free or at a discounted price on this occasion. 

September marks the start of a new cultural season in Lithuania, when theatres, concert halls and other arts venues present new programmes. It's also the time of year for music, film, theatre festivals and exhibitions. 

21 September is the International Day of Peace to promote peace around the world. This day can be marked with educational events, discussions and initiatives that promote a culture of peace and understanding. 

September is also a time of harvest festivals. Although these festivities vary from region to region, they often include fairs selling local produce, handicrafts and cultural performances. 

September also sees a wide range of sporting events, including marathons, cycle races and other sports that promote physical activity and healthy lifestyles.
