Georgia operates two parallel calendar systems that structure its festival life. The Georgian Orthodox Church follows the Julian calendar, placing major religious observances thirteen days after their Gregorian equivalents. Christmas falls on January 7, Easter moves according to Orthodox calculations that often diverge from Western dates by one to five weeks, and the Feast of the Assumption occurs on August 28 rather than August 15. Secular national holidays follow the Gregorian calendar. This dual system means that a visitor in early January encounters both New Year celebrations on January 1-2 and preparations for Orthodox Christmas on January 7, creating an extended holiday period when many businesses close and domestic tourism peaks.
Tbilisoba takes place on the last weekend of October each year, typically the final Saturday and Sunday. The Tbilisi city government established this festival in 1979 during the Soviet period, but its current form dates from the 2000s when it expanded beyond a single-day event. The festival centers on Rike Park, the Bridge of Peace, and the streets of Old Tbilisi, though stages and vendors extend along Rustaveli Avenue to Freedom Square. Attendance reaches approximately 400,000 people over two days according to Tbilisi City Hall figures from 2019. The event showcases traditional Georgian polyphonic singing, which UNESCO inscribed on the Representative List of the Intangible Cultural Heritage of Humanity in 2001. Performance groups from all regions participate, including Svan, Gurian, and Kakhetian ensembles whose vocal techniques differ markedly. Food stalls sell khachapuri varieties specific to different regions: Imeretian round flatbreads with cheese, Adjarian boat-shaped versions with egg and butter, Megrelian double-cheese preparations, and Achma layered cheese bread from Abkhazia and Samegrelo. Wine producers from Kakheti, Kartli, Imereti, and Racha pour samples of wines made in qvevri, the large clay vessels buried in the ground that define traditional Georgian winemaking, itself a UNESCO intangible heritage element since 2013. The festival occurs during rtveli, the grape harvest season that runs from late August through October depending on elevation and variety.
Rtveli itself functions as a diffuse festival period rather than a single event. In Kakheti, the primary wine region accounting for approximately seventy percent of Georgian wine production, harvest activities intensify from mid-September through mid-October. Specific estates and villages organize public rtveli celebrations where visitors participate in grape picking and treading. Kindzmarauli Corporation in the village of Kvareli typically holds such events in late September. Twins Wine Cellar in the village of Napareuli coordinates harvest festivals in early October. Pheasant's Tears, a natural wine producer in Sighnaghi, conducts foot-treading demonstrations throughout the harvest period. These are working events where participants collect grapes in traditional wicker baskets called chala, transfer them to large wooden or fiberglass vats, and crush them by foot. The juice then goes into qvevri for fermentation. Georgian qvevri winemaking involves fermenting white grape juice with skins, seeds, and sometimes stems for extended periods, typically three to six months, creating amber-colored wines with tannic structures unlike white wines made elsewhere. The technical distinction matters because visitors expecting conventional white wine encounter something structurally closer to red wine. Rtveli celebrations include supra, the Georgian traditional feast format with a tamada or toastmaster who directs a sequence of toasts. These supras during harvest season feature new wine called chacha when distilled or young wine from early-picked grapes, alongside mtsvadi grilled over grapevine cuttings, lobio bean dishes, and fresh churchkhela made by dipping strings of nuts into concentrated grape juice called tatara or phelamushi.
Alaverdoba occurs on September 28 at Alaverdi Cathedral in the Alazani Valley, Kakheti region. The cathedral, built in the eleventh century and standing sixty-one meters tall, serves as the seat of the Bishop of Akhmeta. September 28 marks the feast day of Saint George according to the Orthodox calendar, though Georgia observes multiple Saint George feast days throughout the year since he serves as the nation's patron saint. The Georgian name for Georgia, Sakartvelo, derives from "kartvel," which some etymologists connect to Saint George, though this etymology remains disputed. Alaverdoba draws pilgrims from across Georgia and neighboring Orthodox regions. The liturgy begins at dawn and continues through mid-morning. Following religious services, the cathedral grounds host wrestling matches, horseback competitions, and singing. The Alaverdi Monastery historically maintained vineyards and produced wine, a tradition that continued through the Soviet period when the monastery functioned nominally as a museum. Alaverdi wine, traditionally made from Rkatsiteli grapes fermented in qvevri, remained available through state wine enterprises. Post-independence, the monastery resumed winemaking under direct church control. Alaveroba wine sold at the festival comes from monastic production. Food vendors sell kupati sausages, mtsvadi, and khinkali filled with meat and herb mixtures specific to Kakhetian preparation, which includes more summer savory and tarragon than Mtiuletian mountain versions.
Svetitskhovloba takes place on October 14 at Svetitskhoveli Cathedral in Mtskheta, twenty kilometers north of Tbilisi. October 14 marks the feast of Svetitskhoveli, or "Life-Giving Pillar," a name deriving from the cathedral's foundational legend involving a pillar that rose miraculously during construction in the eleventh century. The current cathedral structure dates from 1010-1029, built by the architect Arsukisdze, whose name appears in an inscription on the north facade. UNESCO listed Svetitskhoveli as part of the Historical Monuments of Mtskheta World Heritage Site in 1994. The festival attracts tens of thousands of pilgrims who process around the cathedral grounds carrying crosses and icons. The Georgian Patriarch typically presides over the liturgy. Mtskheta's central square fills with vendors selling churchkhela, gozinaki walnut brittle, kada sweet bread, and tklapi fruit leather. Wine from Mukhrani, Saguramo, and Mtskheta's own limited vineyard areas appears at tasting stands. The confluence of the Mtkvari and Aragvi rivers adjacent to Mtskheta holds symbolic significance in Georgian Christianity, and some pilgrims perform immersion rituals at the riverbank following services. The festival coincides with late harvest in nearby vineyards and the beginning of chestnut season in the surrounding Mtskheta-Mtianeti region.
Keenoba occurs in Tusheti, the remote northeastern mountain region accessible only from late May through October via the Abano Pass. Multiple villages celebrate Keenoba, but the primary observance takes place in Omalo, the largest settlement, during the final weekend of July. Keenoba marks the feast day of various village patron saints, with different communities celebrating on different dates from late July through early August. The Tushetian calendar formerly operated on a system where each village maintained distinct saint day observances separated by several days to allow residents to attend multiple celebrations across villages. Omalo's Keenoba centers on the shrine of Lashari, a pre-Christian deity syncretized with Saint George. The shrine consists of a stone structure where ritual sacrifices of sheep occur. A priest or community elder performs the sacrifice, and the meat is distributed and cooked communal pots. Attendees consume the meat as part of a sacred meal. Beer brewed from local barley rather than wine accompanies the feast because Tusheti lies above the elevation where viticulture functions. The festival includes horse races on the meadows surrounding Omalo and wrestling competitions. Tushetian polyphonic singing differs from Kakhetian and Kartlian traditions, featuring narrower melodic intervals and drone structures scholars connect to Northeast Caucasian musical systems found in Chechnya and Dagestan. Attendance ranges from several hundred to over a thousand people depending on weather and road conditions. The Abano Pass road, built in the 1970s, crosses at 2,926 meters and includes sections without guardrails on slopes exceeding forty-five degrees. The pass closes with the first heavy snow, typically in late October, making summer festivals the only accessible public events.
