About Iran Standard Time (IRST)

Iran Standard Time (IRST, IANA: Asia/Tehran) is the civil time of the Islamic Republic of Iran, set at UTC+3:30 — one of the world's few 30-minute-offset time zones. IRST observes Daylight Saving Time (switching to IRDT = UTC+4:30) from the last Wednesday of the Iranian month of Farvardin (~March 22) to the last Wednesday of Shahrivar (~September 22) per Iranian government calendar (the country abolished DST in 2022 then partially reinstated it for energy savings — the schedule is subject to change by Iranian Parliament Majlis decree). The 30-minute offset is preserved because Iran's central meridian is approximately 52.5°E, between UTC+3 and UTC+4 standard zones, and the Iranian Solar Hijri calendar has its own astronomical traditions for time-keeping. IRST serves approximately 88 million Iranian people across 31 provinces. Major cities: Tehran (8.7M city, 13M metro — capital), Mashhad (3.1M), Isfahan (2.2M), Karaj (1.6M), Shiraz (1.6M), Tabriz (1.6M), Qom (1.2M). Other 30/45-minute offset zones: India (UTC+5:30), Nepal (UTC+5:45), Myanmar (UTC+6:30), Newfoundland (UTC-3:30), Afghanistan (UTC+4:30), Marquesas (UTC-9:30). Affects: Tehran Stock Exchange (TSE) trading, Iranian Solar Hijri New Year Nowruz celebrations.

About Central Africa Time (CAT)

Central Africa Time (CAT, IANA: Africa/Johannesburg, Africa/Harare) is the civil time for Central and Southern African countries, set at UTC+2:00 year-round (no DST). CAT serves approximately 200 million people across: Botswana, Burundi, DR Congo (eastern half), Egypt (since 2014 reverting from earlier DST trial; year-round UTC+2), eSwatini (Swaziland), Lesotho, Libya, Malawi, Mozambique, Namibia (since 2017 reverting from earlier WAT trial; year-round UTC+2), Rwanda, South Africa, Sudan (UTC+2 since 2017), Zambia, Zimbabwe. CAT shares the same UTC offset as Eastern European Time (EET) in winter, Egypt Standard Time (EET-Egypt), and Israel Standard Time (IST). Major CAT cities: Johannesburg (5.6M city, 10M metro — economic capital of Sub-Saharan Africa), Cape Town (4.7M metro), Cairo (10M city, 22M metro — the largest city in Africa and the Middle East), Khartoum (5.3M), Lusaka (2.7M), Harare (1.6M), Tripoli (1.2M), Pretoria (740K).
