Does any know the microsoft recommendation for the maximum permissible downtime for PDC. I need to know this to determine a standard according to which I can decide whether to promote a BDC to PDC for a site or leave the site without a PDC for that time (during which the PDC is taken down for maintenence)

There is no recommendation for PDC downtime. The issue is that no domain changes (account, permissions, etc.) can be made with a missing PDC. If there are multiple administrators that do regular, constant work on domain maintenance issues, you maywant to promote a BDC. If not, then there shouldn't be any problems with taking it down for as long as is needed because users can still authenticate with the BDC and access network resources (unless they are on the PDC!).

I wld like to give a a broad view here.
we have a very large network spanning many continents. the Asian region has around 20 sites . and pdc serving these sites is at a siteA. Now this siteA will be down completely for an hour. Now my question is shd I promote a bdc at another site in Asia to pdc or leave it like that for an hr?
