vss. 22-23 And she called unto her husband, and said, Send me, I pray you, one of the young men, and one of the asses, that I may run to the man of Elohim, and come again. And he said, For what reason will you go to him today? It is neither New Moon, nor Sabbath. . . .

The Shunammite woman sent word to her husband that she was sending for Elisha "the man of Elohim". Her husband was perplexed as to why she would send for "the man of Elohim" because ". . . it is neither New Moon, nor Sabbath." The indication is that both New Moon and Sabbath were times to gather after a holy manner.
