A calendar date is a reference to a particular day represented within a calendar system. The calendar date allows the specific day to be identified. The number of days between two dates may be calculated. For example, "25 March 2024" is ten days after "15 March 2024". The date of a particular event depends on the observed time zone. For example, the air attack on Pearl Harbor that began at 7:48 a.m. Hawaiian time on 7 December 1941 took place at 3:18 a.m. Japan Standard Time, 8 December in Japan.
ISO 8601 is an international standard covering the worldwide exchange and communication of date and time-related data. It is maintained by the International Organization for Standardization (ISO) and was first published in 1988, with updates in 1991, 2000, 2004, and 2019, and an amendment in 2022. The standard provides a well-defined, unambiguous method of representing calendar dates and times in worldwide communications, especially to avoid misinterpreting numeric dates and times when such data is transferred between countries with different conventions for writing numeric dates and times.

Vietnam is a dynamic developing economy with a relatively high growth rate. The energy sector plays a key role in promoting the country's socio-economic development. Vietnam has a diverse energy fuel resource of various types such as coal, natural gas, petroleum, hydropower and renewables such as solar and wind energy. The country has recently been successful in renewable energy deployment, especially solar and wind power development. Coal has been the key power generation source since 2018. Coal accounted for about 30% of installed capacity and 47% of electricity generation in 2021 The high use of coal makes Vietnam an increasingly important emitter of carbon dioxide, contributing to climate change.
Date and time notation in Canada combines conventions from the United Kingdom, conventions from the United States, and conventions from France, often creating confusion. The Government of Canada specifies the ISO 8601 format for all-numeric dates. It recommends writing the time using the 24-hour clock (14:47) for maximum clarity in both Canadian English and Canadian French, but also allows the 12-hour clock (2:47 p.m.) in English.
Date and time notation in the United States differs from that used in nearly all other countries. It is inherited from one historical branch of conventions from the United Kingdom. American styles of notation have also influenced customs of date notation in Canada, creating confusion in international commerce.
In Spain, date notation follows the DD/MM/YYYY format. Time notation depends on the level of formality and varies in written and spoken formats. Official time is given using the 24-hour clock, and the 12-hour clock is often used in informal speech.
Date and time notation in Sweden mostly follows the ISO 8601 standard: dates are generally written in the form YYYY-MM-DD. Although this format may be abbreviated in a number of ways, almost all Swedish date notations state the month between the year and the day. Months are not capitalised when written. The week number may also be used in writing and in speech. Times are generally written using 24-hour clock notation, with full stops as separators, although 12-hour clock notation is more frequently used in speech.
The European Committee for Standardization (CEN) and (CENELEC) adopted ISO 8601 with EN 28601, now EN ISO 8601. As a European Norm, CEN and CENELEC member states are obligated to adopt the standard as national standard without alterations as well.
ISO 8601 has been adopted as BIS IS 7900:2001.
The most formal manner of expressing the full date and/or time in South Korea is to suffix each of the year, month, day, ante/post-meridiem indicator, hour, minute and second with the corresponding unit and separating each with a space:
Nepal uses both the DMY and YMD format when writing dates, and uses 12-hour format for time.
Vietnam utilizes four main sources of renewable energy: hydroelectricity, wind power, solar power and biomass. At the end of 2018, hydropower was the largest source of renewable energy, contributing about 40% to the total national electricity capacity. In 2020, wind and solar had a combined share of 10% of the country's electrical generation, already meeting the government's 2030 goal, suggesting future displacement of growth of coal capacity. By the end of 2020, the total installed capacity of solar and wind power had reached over 17 GW. Over 25% of total power capacity is from variable renewable energy sources. The commercial biomass electricity generation is currently slow and limited to valorizing bagasse only, but the stream of forest products, agricultural and municipal waste is increasing. The government is studying a renewable portfolio standard that could promote this energy source.
