I frequently listen by Internet radio either to the daily Divine Liturgy offered in the Cathedral of the Holy Trinity in Piraeus, or to the daily Divine Liturgy in the Patriarchal Cathedral in Bucharest. Both cathedrals also have full daily services, especially the Patriarchal Cathedral, which has complete Midnight Office, Orthros, Hours, Vespers, etc.
The website of the Trinity-Saint Sergius Monastery indicates that a total of 3-4 Divine Liturgies (2 hours each) are offered in different sanctuaries within the monastery complex everyday, mainly because of the huge brotherhood (300 monks) and large number of visitors everyday. Jordanville, Valaam, the Athonite monasteries all have daily Liturgy, as do so many other monasteries. In the US, the ROCOR Cathedrals in San Francisco and New York have daily Divine Liturgy. The MP cathedrals in London, Paris and some other European cities also have daily Divine Liturgy.
I've been told by Russian, Greek and Romanian Orthodox contacts that in the "old countries", daily Matins and Vespers are common in parishes, and daily Divine Liturgy is offered in numerous cathedrals, many large parishes and most monasteries. It is apparently only the "diaspora" and the New World that have difficulties with maintaining weekday liturgical worship.
