The goal here is a list of all major journal embargoes (the ones that science-health journalists and bloggers typically cover), not a comprehensive list of all sci-health journal embargoes.
Please do not trust this list. At best, this list is a resource to generate dialogue as to an actual or correct embargo, or against which to challenge an embargo time claim.
All times in Eastern time zone.
1 pm — Nature Biotech, Nature Cell Bio, Nature Chem, Nature Climate Change, Nature Comms, Nature Genetics, Nature Geosci, Nature Materials, Nature Nanotech, Nature Neuroscience, Nature Physics, Heredity, Cancer Gene Therapy, Cell Research, EMBO reports, Oncogene (all the Nature research journals http://www.nature.com/authors/submit_manuscript.html#n)
12:01 am — Pediatrics
12:01 pm — Some Current Biology papers (others embargoed for Thursday)

2:40 pm - Translational Psychiatry (NPG)
4 pm — JAMA
5 pm — PLoS Medicine, PLoS Biology, PLoS Neglected Tropical Diseases (as above, official embargo time is 5 pm for all PLoS journals, but unofficially embargo lifts once the paper is published online, which may be as much as an hour earlier. Those on press list are advised to check if paper is online before publishing)
7 pm — All Royal Society journals, including Proceedings of the Royal Society B, Biology Letters, Proceedings of the Royal Society A, Interface
1 pm* — Nature (*due to daylight saving, twice a year the time difference between US and UK is more than/less than 5 hours.)
1:40 pm - Kidney International (NPG)
2 pm — Science Translational Medicine

12:15 am — Journal of Experimental Biology
4:00 pm — JNCI?
5 pm — PLoS ONE (Mon-Fri) (Sort of. PLoS ONE embargoes automatically lift as soon as the paper publishes. For instance, if that happens to be 4:28 pm, you can publish your story at 4:28 pm.)
NO EMBARGOES OR NO STANDARD EMBARGOES:
ArXiv, Astrophysical Journal, Astronomical Journal, Journal of Consumer Research, Physical Review Letters, Geology, AGU journals, ACS journals, ESA journals
Major publishers: Cell, Elsevier, JAMA, Nature Publishing, Public Library, Sage, Wiley, ACS
An embargo time of 12:00 or 0:00 is vague and subject to misinterpretation, so always push press officers to clarify and convert to 12:01 pm or 12:01 am to make the time more clear.
