The place of path of the zero meridian GMT approved 

October 13, 1884

Thousands of tourists are photographed on the line of zero meridian.

The history of establishing the place of passage of the meridian, from which the counting of longitude begins, that is, zero (denoted as zero degrees) is quite ancient, since the calculation of location on the map and the cartography itself has been going on since ancient times.

However, the period of the Great Geographical Discoveries, the expansion of the horizon for seafarers and the growing importance of maritime communications and maritime trade in the economies of many countries around the world, as well as the increasingly perceived need for uniformity of the cartographic system, led to the international discussion about decision on where the zero meridian located.

Today we know that the Greenwich meridian is the zero meridian, that is, the meridian passing through the observatory of Greenwich in the UK. Defining it as zero is not associated with any important geographical calculations and did not require this when choosing it.

This line, in opposite to the line of the equator, is conditional, but it allows to achieve uniformity in cartography and calculus of location. In addition, the establishment of a single zero meridian contributed to the establishment of uniformity in the definition of time, since this line became the conditional point of the initial phase of the Earth’s rotation.

The conventionality of the zero meridian before 1884 led to the fact that many states installed their own zero meridian on their maps, which often passed through the main observatory of these countries. Nautical charts were the first who came to a system of uniformity, since the absence thereof led to certain difficulties and additional time costs. So, obtaining location information from a ship of another state required checking with own maps and shifting one's own coordinate system to another one in the case when both ships used different zero meridians.

Similar difficulties shows up in determining the time, which in the conditions of the development of the railway system, which accelerated the processes of movement between areas, only added confusion.

One way or another, but before the International Agreement on the Establishment of the Greenwich Meridian as Zero on October 13, 1884, for a long time, zero meridians could be found on maps of different countries, running in completely different places. Such places were the island of Rhodes (in the writings of Hipparchus), the island of Fuerteventura on the Canaries, the island of Ferro, Cadiz, Greenwich, Lisbon, Paris, Copenhagen, etc.

As for the Greenwich meridian, it was first installed as a zero in 1851.

Twenty years later, the International Geographical Congress took place in Antwerp, which proposed using the Greenwich meridian as zero on all nautical charts. All subsequent International Geographical Congresses and geodetic conferences continued at their meetings the discussion of the question of the zero meridian on the maritime and geographical maps.

In 1884, at the Washington Conference, which went down in history as the Meridian, it was decided to make the Greenwich Meridian a zero on all maps and recommend that all states follow this.

In addition, one of the most important decisions of the conference was the recommendation to use the Greenwich Mean Time calculator as universal time. The beginning of the average solar (world or universal) day was taken as the time of midnight at the zero meridian, and their duration was calculated from 0 to 24 hours. These and other decisions of the Washington Conference were formalized in the form of a resolution adopted on October 13, 1884.


International Day for Disaster Reduction

The United Nations General Assembly, proclaiming in 1989 the “International Decade for Natural Disaster Reduction”, declared the second Wednesday of October “International Disaster Reduction Day” and decided to celebrate it annually during 1990-1999.

In 2001, the General Assembly decided to continue to celebrate this International Day annually, considering it one of the tools to foster a culture of disaster risk reduction, including natural disaster prevention, mitigation and preparedness.

In 2009, the General Assembly, focusing on the importance of reducing the risk of all disasters, renamed this day “International Day for Disaster Reduction” and decided to celebrate it on 13 October.
