My mother was born in March of 1926, so she was born on June 30th of 20 14. What about the cemetery and burial time?

Look up the "old yellow calendar or perpetual calendar" in Baidu, and you can see that the auspicious day of the ecliptic is to be "buried" on the calendar. You can also simply check the zodiac of the day and avoid the hedged zodiac when it is officially placed. Of course, this is the simplest. In fact, if you buy a cemetery, you can let the gentleman of the cemetery company see which day is suitable and which time is auspicious. Or ask a local gentleman who can tell the time to arrange it. It won't cost much.
