Hello there I'm in urgent need of simulating the unix "date" command in python. How can I simply get the same result than : "date -v-1d" (or date --date '1 day ago' under linux) ? How can I get the day 1 week before, 1 month before, etc, without managing 30 or 31 or 28 or 29 days months, etc ... ? Kind Regards Arnaud
