Hours listed on this calendar are normally MST (UTC-7) or MDT (UTC-6) in Calgary. Usually the 24-hour notation is used (e.g. 20:00 hrs = 8 p.m.)

Any dates for full or new moon are specifically for the Calgary area, so may vary from your calendar. Times for any noted sky objects rising or setting are approximate, usually determined from the Palm OS application "Planetarium" using Calgary's latitude and longitude (that application is listed on the Links page).

Official Time / Date Seconds may be a bit +/- due to possible delay of the internet *. Link here is set for Calgary, check whether MDT or MST at linked site. You can change time zones there. Dates for changes between Daylight Saving and Standard times are listed in this Calgary RASC Calendar site on the Later Events page or, during April and October on the Current Events page

* For very precise timing (for occultation reports, etc), you need to use a shortwave time signal, not this link. See especially p 41 in the 2003 Observers Handbook for more information on Time Signals, etc. Full section on time re astronomy starts p35 - if you have the time;-]
