Time converter app1/31/2024 Gregorian calendar occurred in October of 1582, according to the scheme This application assumes that the changeover from the Julian calendar to the While the Gregorian calendar has a leap year every fourth year except century The Julian calendar has a leap year every fourth year, Identical month names and number of days in each month, and differ only in This application deals with only two: the GregorianĬalendar, now used universally for civil purposes, and the Julian calendar, Various calendar systems have been in use at different times and placesĪround the world. Thus, the day of the week can be obtained from the remainderĬalendar dates - year, month, and day - are more problematic. It is assumed that 7-day weeks have formed an uninterrupted sequence sinceĪncient times. That the time scale that is the basis for Julian dates isĪnd that 0h UT1 corresponds to a Julian date fraction of 0.5. Typically, a 64-bit floating point (double precision) variable can representĪn epoch expressed as a Julian date to about 20 microsecond precision. Julianĭates are widely used as time variables within astronomical software. Almost 2.5 million days have transpired since this date. Julian dates (abbreviated JD) are simply a continuous count of days andįractions since noon Universal Time on JanuBC (on the JulianĬalendar).

It can determine a time zone (in UTC+x format) for a user-selected country and provide a rough estimate for a "PST to UTC+X" time conversion. Thank you for reading my post! Now you know how to create a simple yet useful Time Zone Converter app. Implement more time zone formats, such as GMT, EST, CET, and so on.įeel free to use your creativity.For example, Brazil has four different time zones. This would provide more options for countries and even work with more cities. Some alternatives are TimezoneDB and GeoNames, to name a few. Replace the set of time zones for countries/continents with an API.If you want to improve your Time Zone Converter, here are some suggestions: streamlit folder with this config.toml file Utc_offset = datetime.now(pytz.timezone(timezone)).strftime('%z') St.markdown("# :earth_americas: Corresponding UTC time:") Get the corresponding UTC+x time zone for the user selection # Display the selected UTC offset # Create a dropdown to select a country within the selected continentĬountries = list(timezone_dict.keys())Ĭountry = st.lectbox("2. # Create a dropdown to select a continentĬontinent = st.lectbox("1.

The resulting time for the selected country is displayed in the app.The user enters a PST time to be converted into the associated time obtained from step (2).The corresponding time zone (in "UTC+x" format) is obtained based on the user's selection.The user selects a continent and a country.You can go straight to the app and the GitHub repo, if you’d like to skip reading.īut first, let’s talk about… How does the Time Zone Converter work?
