Time Zones

The predefined locations on this site will have the Time Zone set. For user-entered locations, choose a Time Zone from the drop-down on the custom page. To set the Time Zone in a link, see the FAQ entry.

Around the mid-19th or early-20th century, before the adoption of Standard Time zones, cities and towns used their own local time which was usually based on solar noon of their location. This caused major complications for the railroad companies when making arrival and departure timetables because each town had its own local time which was different from other nearby towns. To ease all the scheduling problems, they created time zones for large areas and set all the local times the same. They did this by making all the clocks in that area (the time zone) have their time offset from Greenwich Mean Time (GMT) be the same as all other towns and cities in the same time zone. The time offset was usually an hour multiple, e.g. +2:00 or -5:00, but a few areas use a fractional part of an hour, such as Newfoundland, Canada at -3:30 and Kathmandu, Nepal at +5:45. These time zones were later adjusted, officially named, and set into law—or adopted—by the government of the country. Most countries or regions have not changed their time offset since then, but many have.

A few smaller areas have chosen their own time offset and daylight saving time (DST) Rules that differ from the geographical or political division that they border or are contained in. For example, the state of Quintana Roo in Mexico has differed from their country and neighboring state’s time offset and DST observance a few times—in 2015 they moved their time offset to -5:00 and stopped observing Mexican DST.

Using the Time Zones defined on this page will allow the calendar to adjust for both Time Offsets and DST rules that vary over time. Our predefined locations, for applicable regions, will have this Time Zone set or you can choose it on the custom page. When a calendar is generated using a rule on this page, it will be shown along with the latitude and longitude information in the header, e.g. Time Zone: America/Cancun. (You must select the “Latitude, longitude and time info” checkbox to see this.)

Our DST page details the DST rules we use during calendar creation—this page documents the more complicated situations.

On this site, we consider GMT and UTC (Coordinated Universal Time) synonymous.

 


 

Time Zones Used While Creating the Calendars

The Time Zone rules have been researched using the IANA time zone tables, Wikipedia, newspaper or other published articles on the internet, or information from the country or city’s website. While there are many more zones defined in the IANA tables, use only the Times Zones listed on this page. Using Time Zones not on this page will be ignored by the code generating the calendar.

The future dates of the time offset and DST observance are set by the government of the country or locality and are subject to change. Also see FAQs and DST adjustments.

The rules on this page will supercede the basic DST rules documented on our DST rules page for all the years from the adoption of the time offset to the year 2099.
