Nativity Fast 2026: Dates, Fish Days and a Week of Fasting Meals
The Nativity Fast 2026 begins on Sunday, November 15, and lasts 40 days, until Thursday, December 24, Christmas Eve. Below you’ll find the full calendar with the 14 days when fish is allowed, what you can and can’t eat, a week of plant-based fasting meals and a Christmas Eve menu.
I grew up in Romania, where most families keep the Christmas fast in some form, and these weeks are still my favorite time to cook: soups simmering on the stove, cabbage rolls in the oven, gingerbread cooling on the counter. I’ve put my fasting week, the shopping list and the recipes into a free printable guide I’ll email to you right away.

When Does the Nativity Fast Start and How Long Is It?
The Nativity Fast, also called the Advent fast or the Christmas fast, always starts on November 15 and ends on December 24, Christmas Eve. In 2026, November 15 falls on a Sunday and Christmas on a Friday.
- Last day before the fast: Saturday, November 14, 2026
- First day of the fast: Sunday, November 15, 2026
- Last day of the fast: Thursday, December 24, 2026 (Christmas Eve)
- Length: 40 days
- Christmas: Friday, December 25, 2026
These are the dates of the Romanian Orthodox Church and other churches on the new (Revised Julian) calendar. Churches on the old calendar, such as the Russian and Serbian churches, keep the fast from November 28 to January 6 and celebrate Christmas on January 7.
Fish Days in the Nativity Fast 2026
In 2026 there are 14 days when fish is allowed: almost every Saturday and Sunday between November 21 and December 19, plus a few feast days during the week. From December 20 until Christmas Eve, there are no more fish days.
| Date | Day | Feast |
|---|---|---|
| November 21 | Saturday | Entry of the Theotokos into the Temple |
| November 22 | Sunday | |
| November 23 | Monday | St. Anthony of Iezer |
| November 28 | Saturday | St. Arsenie of Prislop |
| November 29 | Sunday | |
| November 30 | Monday | St. Andrew the Apostle |
| December 1 | Tuesday | Romania’s National Day (Te Deum) |
| December 3 | Thursday | St. George of Cernica |
| December 5 | Saturday | St. Sabbas the Sanctified |
| December 6 | Sunday | St. Nicholas |
| December 7 | Monday | St. Philothea |
| December 12 | Saturday | St. Spyridon |
| December 13 | Sunday | St. Dosoftei |
| December 19 | Saturday |
This is the calendar of the Romanian Orthodox Church; other Orthodox churches follow the same pattern, with small differences around their own saints. The rules for oil and wine also vary, so if you keep a stricter fast, follow your parish calendar or ask your priest.
My blog is vegetarian, so you won’t find fish recipes here. On the fish days, the fasting menu below works just as well.
What Can You Eat During the Nativity Fast?
On fast days the food is plant-based:
- vegetables, fresh, roasted or pickled (sauerkraut, pickled peppers, cucumbers)
- legumes: beans, chickpeas, lentils, peas
- grains and egg-free pasta: rice, cornmeal, oats, buckwheat, bread
- mushrooms, tofu, textured soy protein
- fruit, nuts, seeds, tahini and halva
- oil, unless you keep the strict fast
You don’t eat meat, dairy or eggs: no milk, cheese, butter, cream or yogurt (soy yogurt is fine), and no foods made with them, like regular mayonnaise or milk chocolate. Read the labels on store-bought cookies, puff pastry and “dark” chocolate: many contain milk or butter.
A Week of Nativity Fast Meals
I cook bigger batches and plan for leftovers, so the dishes marked “leftovers” come from the day before: you only cook once a day.
| Breakfast | Lunch | Dinner | |
|---|---|---|---|
| Monday | oatmeal with apple and walnuts | Creamy Red Lentil Soup | Vegan Falafel with hummus |
| Tuesday | toast with hummus and vegetables | lentil soup (leftovers) | Vegan Cabbage Casserole |
| Wednesday | Veggie-Packed Breakfast Muffins | cabbage casserole (leftovers) | Vegan Bolognese Pasta |
| Thursday | muffins (leftovers) | Romanian Vegan “Chicken” Soup | Vegan Goulash Soup |
| Friday | toast with eggplant and pepper spread | goulash (leftovers) | Lebanese Chickpea Soup |
| Saturday | oatmeal with homemade Nutella | Vegan Greek Moussaka | Three Bean Salad with polenta |
| Sunday | pancakes with jam | Vegan “Meatball” Soup | moussaka (leftovers) |
For dessert: gluten-free vegan brownies or vegan tiramisu. The free guide has this week as a printable page, plus a full holiday menu and 16 recipes.
How to Stay Full on a Fasting Diet
When a fasting meal leaves you hungry an hour later, it’s almost always because the plate was only vegetables. I build every meal from four parts:
- A legume or plant protein: chickpeas, lentils, beans, tofu, textured soy.
- A grain or potato: rice, polenta, pasta, good bread.
- Vegetables, as many as you like: raw, roasted, pickled.
- A good fat: olive oil, tahini, nuts, seeds.
On Sundays I cook a big pot of chickpeas or beans, which keeps 3 to 4 days in the fridge and freezes well in portions. Soups freeze beautifully too, and cabbage rolls, cabbage casserole and goulash are just as good, if not better, the next day.
What to Serve on Christmas Eve
Christmas Eve is the last day of the fast. Many keep it stricter during the day and gather in the evening around a generous fasting table. My menu for 6 to 8 people:
- To start: hummus and roasted eggplant and pepper spread, with homemade bread and pickles
- Salads: vegan Olivier salad and three bean salad
- The main: vegan cabbage rolls (sarmale), with polenta and hot peppers
- Dessert: vegan gingerbread cookies and gluten-free vegan brownies
Make the cabbage rolls two days ahead: they taste better reheated.
