Astro-Calendar: 2020 Feb. / Once-in-Century Palindrome: Feb. 2

Groundhogday2005.jpg
In addition to being Groundhog Day (above, photo of 2005 annual Groundhog Day ceremony on Gobler's Knob in Punxsutawney, Pennsylvania) and Super Bowl Sunday, February 2 is a once-in-a-century, calendar-date palindrome: 02 / 02 / 2020 (palindrome is a sequence of numbers which reads the same forward as it reads backward), and the 33rd day of the year (in the month including the Leap Year Day, February 29), which is followed by 333 more days! The previous calendar-date palindrome was 1111 November 11 (11 / 11 / 1111). The next two calendar-date palendromes will be 2121 December 12 (12 / 12 / 2121) and 3030 March 3 (03 / 03 / 3030).

  2. حصن البيت باستخدام الفيبر ونيل حول محيط المنزل فهو منتج مبيد حشري ممتاز وليس مكلف ويمكن فعله بنفسك.
    ابحث علي الانترنت لمعرفة ومشاهدة بالفيديو كيفية التخلص من النمل الأبيض ليكون عندك خلفية قبل العمل، إذا رأيت أي تلف فسارع بالاتصال المختص لأن هذا التلف يدمر كل اساس البيت، استخدم المبيد الحشري مرة واحدة في الأسبوع، وسد أي فتحة ممكن يدخل منها النمل حمض البوريك.
