Set Apart Days or Holidays? Which days where we commanded to keep?

Ex. 23:13 “And in all that I have said to you take heed. And make no mention of the name of other mighty ones, let it not be heard from your mouth.

14“Threetimes in the year you are to observe a festival to Me:

Three times a year?  I wonder what three times where commded?  Let us take a look and see what scripture has to say.

15 “Guard the Festival of Unleavened Bread. Seven days you eat unleavened bread, as I commanded you, at the time appointed in the month of AÄiÄ – for in it you came out of Mitsrayim – and do not appear before Me empty-handed;
16 and the Festival of the Harvest, the first-fruits of your labours which you have sown in the field; and the Festival of the Ingathering at the outgoing of the year,
when you have gathered in the fruit of your labours from the field.
17 “Three times in the year all your males are to appear before the Master HWHY.
18 “Do not offer the blood of My slaughtering with leavened bread, and the fat of My offering shall not remain until morning.
19 “Bring the first of the first-fruits of your land into the House of HWHY your Elohim. Do not cook a young goat in its mother’s milk.

It is very funny i do not see the normal holidays that christians swear by.  I do not see easter, christmas or new years.  Wow so if they where not commaned why do we keep them?
Because we have learned the ways of the Pagans.
Repent now for the time is at hand.
