It looks like the annual 23rd March parade has been abandoned. Whether for security reasons or as an austerity measure, I would say it is a good move since the whole thing must have cost a fortune. The award giving ceremony that was a part of it is still in place though it now just takes place within the presidency.
Though there have been a number of arts and cultural events lately, I think there should be more (affordable) happenings and ways you can productively use your spare time. I still remember how much we used to enjoy the trade shows and other such events while in England and though not as grand, the expos in Japan and Singapore were a nice way to spend the day.
