How to find auspicious time to tie Rakhi:
Please visit panchang and Looks for your city and click on it. Select Amavasyant or poornimant panchang. Look for Auspicious AJ: Abhijit muhurtha time to tie rakhi. Now remove inauspicious RK:, DM:, YM: timings from AJ: time's overlap. Also If you are in india tie rakhi after K:Vishti time. After 2:35PM in india. For other countries one can look into our panchangam for your city and tie after Visthi karana (K:Visthi). This is not required. One can tie raksha anytime. This method is given for those who wants to tie rakhi in auspicious time.
