Time Zone Lookup
Under normal circumstances, you don’t need to change the time zone offset that appears after you enter your birth location in the Free Natal Chart Report tool. Please don’t adjust the time zone offset unless you know for certain what you’re doing since the default offset incorporates crucial factors such as daylight savings time and is in the vast majority of cases accurate.
However, if you’d like to check up on your time zone offset value, you can use the form below:
Please note that if, for example, your result is Eastern Daylight Time, you will see the value of -5:00:00 in the Raw Offset field and a value of -1:00:00 in the DST offset field. This is the reason the UTC offset value for Eastern Daylight Time is -4 instead of -5. You need to add together the Raw Offset and DST Offset fields to arrive at the correct value.
It’s important to note that tools such as the one above are based on current time zone projects from the non-astrological community. While the data is well-researched back until 1970, before that date, time zones are far less reliable. In sum, use these types of tools for astrological reasons with reasonable confidence for birthdates after 1970, and skeptically for dates before 1970.
