Shri Dev Kaaldarshak Panchang 2019 / Calendar 2019 - 5 Pcs The Hindu calendar is based on lunar months corresponding to the phases of the moon. Most of the Hindu festivals are determined based on position of the Sun and the Moon. Here we present a month wise calendar of Hindu festivals, including cultural and religious occasions for 2019 (Saka Era: 1940 / Vikram Era: 2075-76). A calendar is a system of organizing days for social, religious, commercial or administrative purposes. This is done by giving names to periods of time, typically days, weeks, months, and years. A date is the designation of a single, specific day within such a system. A calendar is also a physical record (often paper) of such a system. A calendar can also mean a list of planned events, such as a court calendar or a partly or fully chronological list of documents, such as a calendar of wills.
