Periodicity of Deliveries - Findings from Six Selected North Indian Hospitals.

We present here a report, based on data obtained from six selected North Indian hospitals, on variations in the number of human deliveries over the period from 1 October 2010 to 30 September 2011. We tried to identify whether there are any cycles exhibited by the data. We discover cyclicity over different months of the year and days of the week whereas cyclicity over different phases of the lunar cycle is not clearly established.
