Yom Tov and Chol HaMo'ed

Laws of Yom Tov:

Any work that is not allowed to be done on Shabbat should not be done on a Yom Tov (holiday), with some exceptions. Yom Tov differs from Shabbat with regard to cooking, carrying, and lighting a fire. However, these things have a special way in which you are allowed to do it in.

Cooking is allowed only if you are cooking for that day. You are not allowed to cook on the first day of Yom Tov for the second day. In the Jewish calendar the day starts at night, therefore, you are not allowed to start cooking unless you have lit the candles for the second day of Yom Tov. For example, for this year, the first day of Pesach falls out on Monday night and Tuesday day. You are not allowed to cook for Tuesday dinner until you have lit the candles at 8:04pm. But if you cooked something on the first day (Tuesday) and you ate it on that day and have extra, you may eat that on the second day (Wednesday).

Carrying is allowed only if you are carrying the things that you will need. For example, if you need keys, then you can carry them. You have to make sure to use them and to carry only the key needed. Same goes for anything else that you need. Ex: food, clothing, etc. It's best if you carry with a difference, meaning not to carry the way you would everyday, but do it with a change.

Lighting a fire is allowed only if you light from a pre-existing fire. You can light the stove only if you have a pilot stove, meaning that there is a fire already burning. Extinguishing fire is forbidden. Also, once the fire is lit, the flame should not be lowered. You can only make it higher.

Laws concerning washing dishes is as follows: You are not supposed to wash dishes on the first day of Yom Tov in order to be used for the second day, just like cooking. Therefore, you can wash the dishes right before using them.

You are not allowed to carry, cook, or light a fire for a non-Jew.

Laws of Chol Hamoed (Intermediate Days Of a Holiday):

Since these days are part of the holiday, it is better if we don't do work that is hard. If a financial loss will occur, then you can work.

You shouldn't do any garden work.

You shouldn't get haircuts (shaving), but you are permitted to shave for the last two days of Yom Tov.

You should not cut your nails unless you have cut them a day before Yom Tov.

You are not allowed to do laundry, even for clothing that is needed for the last two days of Yom Tov. You are allowed to do laundry for babies and small children, since they get dirty fast.

If you need to record things, you can write with a change, either in how you hold the pen or change the hand you write with. If it's not necessary, then you shouldn't write.
