NYTIMES article here: http://www.nytimes.com/2011/12/15/world/europe/boris-chertok-russian-rocket-engineer-dies-at-99.html?_r=1&ref=science By an odd coincidence, Boris Chertok was born in Lodz, now Poland, then Russia, my dad's birthplace, nine years to the day after my dad---assuming the date provided in the article is in New Style. My dad was born Feb 16, 1903 Old Style, which converts to March 1 in non-Leap Years and Feb 29 in Leap Years. Chertok's March 1 birthday was in a Leap Year and my dad's was not, so their birthdays would have been a day apart if the NYTIMES date was converted from Old Style: Dad: Feb 16, 1903 Old Style ---> Mar 1, 1903 New Style Chertok: Feb 17, 1912 Old Style --->: Mar 1, 1912 New Style So in New Style they have the same birthday, in Old Style they're a day apart. Old Style was in use until after the Russian Revolution in 1918 or thereabouts. _______________________________________________ Seesat-l mailing list http://mailman.satobs.org/mailman/listinfo/seesat-l
