Daylight Saving Time Ends

Drivers beware. After the time change this weekend the sun's location will shift and glare may affect you differently on your daily commute.

November 2010 Sunrise/Sunset Tables

Sample sunrise/sunset tables for select cities in Canada, the US, the Middle East and Haiti have been posted for November 2010. The tables include the times of rise and set as well as the time of solar noon and the total number of daylight hours for each day of the month.

If your location is not one of the samples, contact us for a free table for your location for this month.

Visit http://www.sunposition.com/tables.html to view our samples or to order your specific table.

If you prefer, our tables can be prepared showing the sun's direction at rise and set (instead of the time of solar noon and the total number of daylight hours).

Cheers, Ralph

Air India Memorial Sundial Repaired in Time for 25th Anniversary Ceremonies

In early 2007 we had the privilege of designing the sundial feature for the Air India Flight 182 Memorial in Toronto.  The sundial was unveiled by Prime Minister Stephen Harper on June 23, 2007, the 22nd anniversary of the bombing.

And on June 23, 2010, the Prime Minister was again on hand, this time for the 25th anniversary ceremony.

Five day later, on June 28, 2010, Indian Prime Minister Manmohan Singh visited the memorial and participated in a private remembrance with representative victims' family members.

Although the sundial had been vandalized in the Spring of 2010, repairs were made just in time for the 25th anniversary.  For further information about the Air India Memorial Sundial see the following:

Peak UV Times

Our sunrise/sunset tables can be used to determine the time of peak UV radiation in your area.  Simply look up the time of Solar Noon on our tables - this happens to coincide with peak UV time.  Just remember to add one hour to our tables if Daylight Time is in effect.

Take precautions 2-1/2 hours either side of solar noon.  For example, solar noon occurs in Toronto tomorrow at 1:25 p.m. EDT, therefore, the danger period runs from about 11:00 a.m. to 4:00 p.m.

For a free sun table for the current month in your location visit our Sun Tables page at http://www.sunposition.com/tables.html

Environment Canada states:

• "The amount of UV you receive depends on both the strength of the sun's rays (measured by the UV Index) and the amount of time you spend in the sun. Reduce your time in the sun – seek shade, particularly between 11:00 a.m. and 4:00 p.m. from April to September.
• Cover up, wear a broad-brimmed hat, a shirt with long sleeves and wrap-around sunglasses or ones with side shields
• Use sunscreen – with a sun protection factor (SPF) of 15 or higher, with both UVA and UVB protection. Apply generously before going outside, and reapply often, especially after swimming or exercise
• Listen for Environment Canada’s UV Index – it’s included in your local weather forecast whenever it is forecast to reach 3 (moderate) or more that day."

Daylight Saving Time

For those of you in North American jurisdictions that observe Daylight Saving Time, don't forget to 'spring' your clocks forward one hour this Saturday night! Official time change occurs at 2:00 a.m. local time on Sunday, March 14th.

Starting in 2007, daylight time begins in North America on the second Sunday in March and ends on the first Sunday in November. On the second Sunday in March, clocks are set ahead one hour at 2:00 a.m. local standard time, which becomes 3:00 a.m. local daylight time. On the first Sunday in November, clocks are set back one hour at 2:00 a.m. local daylight time, which becomes 1:00 a.m. local standard time.

Not all places in the U.S. observe daylight time. In particular, Hawaii and most of Arizona do not use it. Indiana adopted its use beginning in 2006. In Canada, most of Saskatchewan, parts of Quebec, and Southampton Island in Nunavut do not observe daylight time.
