Recurring-call calendar

Annual and periodic calls no API lists for us: fellowships, early-career awards, prizes, SBIR/STTR rounds, space programmes and synchrotron/neutron beamtime. Each entry links to the funder's official page and shows the date we last checked it. Where the funder has not published the next date we say “check the funder page”. We never guess dates.
